London Mithraeum

The ruins of a church dating back to Saxon times, rebuilt by St Dunstan in 950, destroyed in the Great Fire of London, and then rebuilt by Sir Christopher Wren in 1697. Most of the church was destroyed during the blitz, leaving only the tower (dating from Wren's time) and hollowed-out walls (from an 1817 reconstruction). The ruins are now overgrown with picturesque vines and trees, and were converted into a public garden in 1967, complete with benches.

A 900-year-old tree stump carved and painted to feature elves and small animals.

In many cities a local transport museum would be of very narrow interest - not London, however! London's public transport is iconic, and the story of how it developed from horse and cart through early buses, Tube trains and trolleybuses to the present day is well worth coming to find out about. There is plenty of opportunity to clamber aboard the historic buses and Tube trains on display. Also, because London's transport is so well known, the museum shop contains plenty of items that make interesting and original gifts and souvenirs.

A historic boat, part of the Imperial War Museum.

The oldest church in the City, founded by Saxon abbots in 675 AD.

A vast collection of cartoons and comics on display with special, often topical, exhibitions.

London Stone is a historic landmark housed in a public display case at 111 Cannon Street in the City of London. It is an irregular block of oolitic limestone measuring 53 × 43 × 30 cm (21″ × 17″ × 12″), the remnant of a once much larger object that had stood for many centuries on the south side of the street.

A vast repository of the world's cultures, controversially including hundreds of items that were looted from their places of origin. Entire sections are devoted to Egyptian, Greek, and Middle Eastern artifacts, as well as the piece which united them all, the Rosetta Stone. Other items on everyone's list are the largest collection of mummies outside Egypt and the Elgin Marbles. The collection also includes some of the world's finest collections of Chinese and Sub-Saharan African art; perhaps the most famous of the latter are the Benin bronzes. A definite highlight of a trip to London. Temporary exhibitions are invariably excellent and meticulously researched, but can be expensive. It has a fine store, mainly selling replicas of items in the collection.

The remains of the once-magnificent palace, home to English kings since Edward I, adjoin Richmond Green, a pleasant open green space and historic cricket ground. Only the Gate House and Wardrobe, now converted into flats, remain.

A modest museum covering local history which relocated in 2010; has an excellent cafe.

Properly St Lawrence Jewry next Guildhall, it is the official church of the Lord Mayor of London.

After leaving its brutalist skyscraper on Old Broad St, the London Stock Exchange now resides on Paternoster Sq. Dating back to 1698, it is one of the world's oldest and largest stock markets.

Su Catholic Church of England with bells and smells (incense). There is an impressive model of the old London Bridge.

One of the "Magnificent Seven" old cemeteries in London. Graves range from plain to ornate and the site can be a tranquil place to walk amid the bustle of the city. It was opened in 1840 and is still a working cemetery, although it was closed for some time in the late 20th century. Can be nice, if morbid, for an afternoon stroll, especially as a route (and cycle route) between Old Brompton Road and Fulham Road.
