Chapter House of Old St. Paul's
Old St. Paul’s is a name used to refer to the Gothic cathedral in the City of London built between 1087 and 1314. At its peak, the cathedral was the third longest church in Europe and had one of the tallest spires. The cathedral was destroyed in the Great Fire of London of 1666, and the current domed St. Paul’s Cathedral — in an English Baroque style — was subsequently erected on the site by Sir Christopher Wren.
