Tallest building in Europe opens

Europe's tallest building, the Shard in London, will be officially opened with a massive display of lights and music.

It's 310 metres tall, and cost one-and-a-half billion pounds to build.

It'll have offices, restaurants and a hotel, as well as some seriously expensive flats - each costing about fifty million pounds.

There's still work to be done inside. The whole interior will be finished by next year.
