Chester Square is a small residential garden square located in London's Belgravia district. Along with its sister squares Belgrave Square and Eaton Square, it is one of the three garden squares built by the Grosvenor family when they developed the main part of Belgravia in the 19th century. Chester Square is named after the city of Chester, near to which Eaton Hall – the ancestral home of the Grosvenor family – is situated.
St. Michael's Church
The Anglican Church of Saint Michael in Chester Square was built in 1844 along with the rest of the square, and consecrated two years later. The Ecclesiologist magazine criticised the opening, saying it was "an attempt - but happily a most unsuccessful one - to find a Protestant development of the Christian styles". The church is in the late Decorated Gothic style, with an exterior of Kentish Ragstone. The architect was Thomas Cundy the younger.
