Greatest "free" bar view over London. The Heron Tower is a commercial skyscraper in London. It stands 230 metres tall including its 28-metre mast making it the tallest building in the City of London financial district and the third tallest in the UK.
The AA is Britain's oldest school of architecture, but anyone can take advangte of the great work going on there. You can catch really interesting public lectures and free exhibitions throughout the year. There are also occasional installations and event launches, a bijoux cafe and brilliant bookshop. A great place to hang out with the builders of the future.
