High above the skyline of the Russian city of Yekaterinburg, this incomplete tower stands testament to what can be achieved with an amazing vision and poor financial planning.

At 220 metres, it is only half of its planned height of 400 metres, which would have made it one of the tallest towers in the world. It was also planned to include a revolving restaurant - something to rival the 540 metre high Ostankino Tower in Moscow.

Although construction began in 1983, by the end of the decade it had ground to a halt, much to the dismay of investors, but to the infinite joy of thrill seeking base jumpers¹, made easier by the lattice-work of metal to climb inside. By 2000, the number of people tragically dying from the tower forced the authorities to weld the doors shut.

Today it remains, rather eerily over the city, as these photos show.
