Which English architect designed St Paul's Cathedral in London after the Great Fire of 1666?

Christopher Wren designed St Paul's Cathedral in London after the Great Fire of 1666.

Wren's cathedral replaced an earlier medieval St Paul's that was severely damaged in the fire. Construction of the present building began in 1675, and the cathedral was completed in 1710. Its great dome became one of London's defining landmarks.

The building is an English Baroque masterpiece rather than a Gothic cathedral. Wren combined a monumental classical exterior with a vast interior, using a three-shell dome whose inner and outer structures serve different purposes. The dome rises above the crossing and is topped by a lantern and golden cross.

Wren was both an architect and a scientist, and he oversaw the rebuilding of many London churches after the fire. A common mix-up is attributing St Paul's to a medieval architect: the current cathedral is an early modern rebuilding, not the surviving medieval structure.
