Parliament Hill is an area of open parkland in the south-east corner of Hampstead Heath in north-west London. The hill, which is 98 metres high, is notable for its views of the capital's skyline. Many landmarks can be seen from its summit such as Canary Wharf, the Gherkin, the Shard and St Paul's Cathedral. The Houses of Parliament which are 6 ⁄4 miles south in the City of Westminster can still be seen from Parliament Hill although they have become rather obscured by surrounding buildings.
