Temple Church (St Mary's). The Temple Church is a late 12th-century church in London located between Fleet Street and the River Thames, built for and by the Knights Templar as their English headquarters. In modern times, two Inns of Court (Inner Temple and Middle Temple) both use the church. It is famous for its effigy tombs and for being a round church. It was heavily damaged during the Second World War but has been largely restored. The area around the Temple Church is known as the Temple and nearby is Temple Bar and Temple tube station.
