Tower Bridge: Opened in 1894 as the perfect example of old and new. The style of the bridge was meant to blend with The Tower of London. Yet its hydraulic system as well as bascule (counterweight) style were impressive for the Victorian age.
The Shard: Opened in 2013, The Shard's design caught many of guard. Designer, Renzo Piano called it a shard of glass through the heart of historic London. The Shard is energy efficient with its own combined heat and power plant.
