20 Fenchurch Street

20 Fenchurch Street
Avoid the death ray

20 Fenchurch Street has been nicknamed The Walkie-Talkie because of its distinctive shape. Designed by architect Rafael Viñoly, construction was completed in Spring 2014, and the top-floor public accessible'sky garden' was opened in January 2015. The 34-storey building is 160 m (525 ft) tall, making it the fifth-tallest building in the City of London. During the building's construction, it was discovered that for a period of up to two hours each day if the sun shines directly onto the building, it acts as a concave mirror and focuses light onto the streets to the south. During the summer of 2013, the reflection of a beam of light up to six times brighter than direct sunlight damaged vehicles parked on the street nearby and scorched the doormat of a shop in the affected area.
