Last Saturday, millions of people participated in Earth Hour by switching off their lights and reducing their electricity use. But it wasn’t just homes and apartment buildings that cut their energy. Many of the world’s monuments and landmarks turned off their lights, helping to set new records. Here’s how five countries celebrated Earth Hour.

Canada
On Ottawa’s Parliament Hill, there was a candlelight vigil at Centennial Flame. According to Toronto Hydro, the largest city in Canada reduced its power usage by six per cent.

Scotland
The lights were switched off at Edinburgh’s famous buildings, including Edinburgh Castle, the Palace at Holyroodhouse and the Scottish Parliament. In the highlands, the Highland Council’s Ranger Service led a nocturnal wildlife walk, a stargazing event and a ghost walk in the dark.

Singapore
In Marina Bay in the southern part of Singapore, there was a launch of the movie The Amazing Spider-Man 2, as well as live music, food and a sustainable dance floor that lit up using the dancers’ kinetic energy.
