This is Todaiji Temple in Japan, which is reputedly the largest wooden building in the world and houses another very large Buddha (under a roof though - how inconsiderate).

Actually, I could well believe this is indeed the biggest wooden building, as Europe’s largest wooden building would probably fit into Todaiji’s courtyard.

Thanks to Chris Westbrook who found this for us!

Machu Picchu, the “Lost City of the Incas”, is an ancient ruined city found at the top of a mountain. It was probably built around 1440 and the most impressive thing is that it’s all still there, despite being constructed with stones neatly slotted together - there’s no mortar of any sort.

You can follow the switchback road all the way down the mountain to the Urubamba River and north east to the little village of Aguas Calientes. The road is named the Hiram Bingham Highway, after the Yale archaeologist who re-discovered this site in 1911 and promptly pinched hundreds of ancient artefacts (Wikipedia.)
