Open House London is an annual two-day event where more than 800 buildings in the capital are opened to the public, and all for free! There really is something for everyone from Government buildings to private houses, places of worship to hotels and offices, from the very old to the very new. Despite a hectic weekend I squeezed in visits to the Foreign & Commonwealth Office, St Paul’s Cathedral, Middle Temple Hall (one of the four Inns of Court), Temple Church (built by the Knights Templar in the 12th century) and the Supreme Court (the highest court in the land). Quite a variety of styles of architecture! The Supreme Court was particularly interesting, but it was probably Middle Temple that I’d been keen to see for the longest (having already been to Inner Temple for a dinner for barristers guests). Temple Church is a real gem too, containing effigy tombs of medieval knights.
