John Foster Jr (architect)

This is about the architect. For his father, see John Foster, Sr.

John Foster, Junior (1786 – 21 August 1846) was an English architect based in Liverpool. In succession to his father, he was Surveyor to the Corporation of Liverpool (1824–1835). His work, mainly in the Greek Revival style, focused on public buildings and Anglican churches.

In 1812 Foster travelled to Greece and joined Charles Robert Cockerell at the Temple of Apollo Epicurius in Bassae, where the expedition removed the sculpted frieze. The antiquities were clandestinely shipped to Zakynthos and later sold at auction in London. Contemporary accounts and modern scholarship describe the removal as smuggling and plunder, and in 1815 the British Museum purchased the frieze from Foster and his associates.
