This is the Homomomomonument, er… we mean the Homomonument, in Amsterdam.

Unveiled in 1987, the humorously-named monument serves as a very serious memorial to the many thousands of gay men and women who were murdered during the Second World War.

Homomonument consists of three pink granite triangles, which each form the point of one much larger triangle.

The eastern triangle steps down into the canal, pointing to the National War Memorial at Dam Square. The northern triangle points to the Anne Frank House, and finally the south-western triangle points to the offices of the Center for Culture and Leisure - the world’s oldest continuously operating lesbian, gay, bisexual, and transgender/transsexual organisation.

More information about the Homomonument is available on the monument’s offical website, as well as on Wikipedia.

A star fort or trace italienne is a type of military fortification first introduced in Italy around the mid-fifteenth century. Traditional medieval castles, towers and ring forts had proved extremely vulnerable to increasingly mobile cannons, and star forts were introduced specifically to better defend against them.

The tiny Italian town of Palmanova was founded in 1593, and using all the military innovations of the 16th century was built in the shape of nine-pointed star. You can still see quite clearly how the shape of the ramparts allows the points of the star to defend each other. Originally a moat surrounded the town (which partially remains today), and three heavily guarded gates (1, 2, 3) were the only way in.

Cannons were most effective when they were fired perpendicular to the walls of the building under attack, and the star shaped design meant that to best position their weapons, attacking forces would have enter the space between the points of the star - where they would be fired on from both sides!

The judicious use of moats could further thwart the attacking forces, as demonstrated superbly here at Naarden, Netherlands.

By the late seventeenth-century star forts reached the pinnacle of their development, as shown by this complicated example in Bourtange, Netherlands, which has been fully restored to how it would have been in 1742. Here we can see that the design provides defence in depth, with tiers of ramparts that an attacker would have had to overcome to be in with a chance of taking the fort.

This ingenious design quickly became the gold standard for defensive forts, and went on to spread across Europe and the Americas:

<br/> Fort Manoel, Malta (Wikipedia)

<br/> Fort McHenry, Maryland (Wikipedia)

<br/> Fort Jay (Wikipedia) and Fort Ticonderoga (Wikipedia), New York

<br/> Castillo de San Marcos, Florida (Wikipedia)

The design even reached South Africa, where today the Castle of Good Hope can be seen right in the middle of the city! It used to be on the coast, but land reclamation allowed the city to expand around it.

In the nineteenth century the development of the exploding shell changed the nature of defensive fortifications forever, and the star fort soon became utterly obsolete. Which is why several are today used for completely different purposes - like this example in Slovakia where they now spend their time trying to keep people inside rather than out.

And finally, what is probably the world’s most famous star fort isn’t actually known for being a star fort at all - as Fort Wood is today the distinctive star-shaped pedestal underneath New York’s Statue of Liberty.

We’ve previously featured just one star fort several star forts, including Kastellet in Copenhagen, Citadel Hill in Canada, and the aforementioned Fort McHenry in Maryland. If that’s not enough, there’s a whole page about them at Wikipedia too.

Originally conceived by the philosopher Jeremy Bentham in 1785, the panopticon was intended to be a type of prison that allowed the guard to observe any of the inmates without them knowing if and when they were being watched. The design features a central platform surrounded by a ring of cells - thus enabling a clear view of every prisoner.

A panopticon was never built in Bentham’s lifetime, but the idea was revived many years later for the design of Statesville Correctional Centre in Crest Hill, Illinois. Opened in 1925 it has two ’roundhouses’, and is the only working example of a panopticon in the United States. Here’s a great photo which clearly illustrates what the interior is like.

Although genuine panopticons are very rare, outside of the US there are a few more for us to see.

The Presidio Modelo on the Isla de la Juventud in Cuba was directly inspired by Statesville, completed in 1931, and remains one of the best examples of Bentham’s concept. Originally holding up to 6000 prisoners, its most famous inmate was probably the current President of Cuba, Fidel Castro, who was held here between 1953 and 1955. The last prisoner was released in 1967 however, and it is now a national museum - this photo shows how it looks inside today.

Chi Hoa prison in Ho Chi Minh City, Vietnam, is an outdoor version of the panopticon, but still has the central observation tower and cells ringed round it. During the Vietnam War, the prison was used to hold Viet Cong members, and still serves as the main correctional facility for the city.

Finally, Holland actually has three panopticons - in Haarlem, Breda and Arnhem. Designed by Willem C. Metzelaar, Haarlem’s domed prison has four floors of cells, and was completed in 1901.

Merzelaar’s father was the architect for Breda and Arnhem, which perhaps explains the similar style of the three buildings. The Dutch government refurbished these prisons in 1979, choosing to remove the central observation platforms, but keeping the rings of cells intact.

Wikipedia has more on panopticons, Jeremy Bentham and the Separate System.

On a rooftop in the Netherlands we find a blurry picture that may, possibly, if-you-squint-your-eyes, might appear to be two people that are lying very close to each other.

Now, I’m not going to speculate what these people are doing in the privacy of their rooftop. In fact, I’m not even sure that there’s more than one person there!

For all we know this is just some run-of-the-mill topless sunbathing, right? I mean, what else could it be?

In the yard of Scheveningen prison, the Hague, the incredibly high resolution aerial photography has captured this prison inmate doing press ups!

As an aside, this is actually the prison where the former communist President of Serbia and Yugoslavia Slobodan Milošević was held for 5 years before his death in March 2006, shortly before his trial was due to end.

This is the bizarre Spiral Jetty, a huge piece of land art on the northeastern shore of the Great Salt Lake in Utah. Built of mud, salt crystals, basalt rocks and earth, it forms a 1500 foot long (~450 metre), 15-foot wide counterclockwise coil, which extends from the lake shore. It was actually entirely submerged by rising lake waters for many years, but due to lowering water levels, has since re-emerged.

Spiral Jetty was built all the way back in 1970 by the late American sculptor Robert Smithson, who also created some other pieces of land art which are still visible on Google Earth, including the 1971 piece Spiral Hill, Broken Circle in Emmen, Holland.

See other spirals on GSS, and read more about Spiral Jetty at Wikipedia.

Yes people, there really is an absolutely enormous seal in The Hague, Netherlands. Apparently it belongs to the International Fund for Animal Welfare, and presumably it’s designed to so utterly terrify the seal hunters that they’re unable to ever again harm another seal pup…

However that doesn’t explain why someone else in the Hague has another¹ gigantic seal in their back garden! I’m thinking guard dog. Erm… guard seal.

Thanks to Felippo.

With high-resolution images all over the globe, Google Earth has captured many sporting events actually in-progress, so today we proudly present - The Top 10 different sports you can actually see people playing on Google Earth!

As a bonus, we’ve tried to work out how each game is going, and to make things even more difficult for ourselves, we’ve limited our search to ballgames only.

10. First let’s look at the 2nd of the 18-hole Las Vegas Country Club Golf Course, where we see the pin lying on the grass and the person closest playing their putt. Everyone else is standing around, probably telling him to hurry up.

9. As the world’s most popular sport, there must be hundreds of games of football being played at any one second. Here we see students playing “the beautiful game” at the University of Tokyo. However, this looks like it’s just a practise session as there’s no goalie at either end.

8. There’s people playing tennis all over the globe but for the top 10 we’ve chosen these two games of doubles being played on clay in Germany.

The eastern game is in full swing, and on the western court the players are standing in their service positions, and judging from the shadows it looks as if the southern team are about to serve!

7. There’s a good turnout for Lawn Bowls at Bell Vue Park Bowling Green in Newport, Wales. Sadly the bowls are just too small to be seen so we can’t tell how the games are going.

6. The stands are filling up at Yankee stadium, and there’s a couple of people on the field, but we’re a little too early for the game.

Hmm, we’ll need another baseball game in progress… here’s four!

In the thumbnail we see a batter up at the plate, and I think the bases are loaded.

5. The Shay in Halifax, England is also used for football games, but today it’s a home game for local rugby league team Halifax RLFC.

The ball is probably somewhere in the west of the pitch and the team to the north are on the offensive.

4. They’re playing lacrosse in Salamanca, New York. You can tell that it’s a men’s game as there are 20 players on the pitch (women’s lacrosse would have 24 players).

3. Here is a cricket match being played in the village of Hoylandswaine, north of Sheffield. It looks like they’re between plays, as the batsman has stepped back from the wicket to the west and we can see the other batsman and the bowler at the eastern end.

2. Here we see a packed gameday at Seahawks Stadium (now Qwest field) with 63,588 people watching the Nevada Wolf Pack at Washington State Cougars on August 31, 2002.

Google Earth Community member GEChump managed to identify the exact play seen in the photo, making this 11:37 remaining in the second quarter with the game tied at 7.

The Cougars eventually went on to win 31-7.

1. Finally, we find a tense one-on-one street-Basketball game being played in Rolde, Netherlands. Due to the left-hand player’s poor defence the right-hand player has just taken a shot at the basket, however they’ve missed and the ball is rebounding back.

Have you found a ball game on Google Earth not mentioned here? Let us know!
