The London Mithraeum is a 3rd century Roman mithraeum that was discovered in Walbrook during construction work in 1954. The entire site was relocated several times before being returned to its original site as part of the new Bloomberg building. This temple of the mystery god Mithras became perhaps the most famous 20th-century Roman discovery in London. In addition to the temple structure, there is a display of Roman artefacts found on the site and a contemporary art exhibit responding to the site. Visitor numbers are limited and timed slots are often fully booked up several weeks into the future so plan well ahead.

The headquarters of world's most famous insurance market, housed in a revolutionary (at the time) bizarre, Matrix-like glass-and-steel building designed by Richard Rogers, with all support services (lifts, ventilation, etc.) suspended outside. Recognised as a masterpiece of exoskeleton architecture.

This is probably the most famous criminal court in the world, and has been London's principal criminal court for centuries. It hears cases remitted to it from all over England and Wales as well as the Greater London area. The present building dates largely from 1907 (a new block was added from 1970 for more modern facilities) and stands on the site of the infamous medieval Newgate Gaol. The Central Criminal Court is of course best known today for its association with John Mortimer's Rumpole of the Bailey character, novels and television series. Daily case listings are available at The law pages. No bags, cameras, drinks, food or mobile phones—no facilities for safekeeping. Children under 14 are not admitted.

A small realm of serenity in the midst of the typical turmoil. It used to be the court of the Knights Templar. You can still visit the beautiful Romanesque church, which is one of the oldest ones in London (opened in 1185) and has connections to the order of Templars. The chancel of the church was built by Henry III. The church still serves the members of Gray's Inn and Lincoln's Inn and has frequent services open to the public. Fans of Dan Brown's The Da Vinci Code will recognise the church from both the novel and the film.

A lovely park on the southern banks of the Thames known or its wildlife and some splendid examples of mature trees.

Fine stone bridge linking Twickenham/St Margarets with Richmond. It is the oldest surviving Thames bridge in London, dating from 1777.

The TfL-backed Hidden London offers tours around the disused Aldwych tube station which had its own branch on the Piccadilly line. The tour explains the station's unusual history including its use for protection (for both people and historical artefacts held by the British Museum) from the Blitz during WWII. More recently, it was used as a filming location and for testing station equipment and decor. Of note, it was used for filming James Bond: Die Another Day, V for Vendetta and the Prodigy music video for Firestarter. Tours are roughly an 1 hour and 15 minutes long, wear sturdy shoes (not sandals).

The main headquarters of the Worshipful Company of Fishmongers and a Grade II* listed building.

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.

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

Not as popular with tourists as St Paul's north of the river, Southwark Cathedral has been the site of worship since the year 852. Literally in the shadow of London Bridge, the Cathedral is a shelter from the noise of the city. Next to the Cathedral is the Borough Market open Th-Sa with a wide range of speciality food to buy, a good area for lunch.

A neoclassical triumphal arch, designed by Decimus Burton and first erected in 1826 as a grand entrance to Buckingham Palace. From 1846 onwards, the arch was topped with a massive equestrian statue of the Duke of Wellington - a major road widening of Piccadilly in 1882 was the opportunity to finally remove the over sized statue to Aldershot. The present magnificent statue Peace Descending on the Quadriga of War was placed on top of the Arch in 1912, and remains today the largest bronze sculpture in the United Kingdom, spectacularly lit at night. During the 1950s, the arch served as the smallest police station in the city, when it was occupied by ten constables, two sergeants and a cat! The arch was opened to the public for the first time in 2001 after a £1.5 million restoration by English Heritage. (Wellington Arch is also available for corporate and private events, with dramatic views down Constitution Hill and across central London from the Arch's spacious balconies, Wellington Arch is a novel and unique place to impress your guests).

Remains of the wall that surrounded the City of London for almost two thousand years. The parts around the Barbican are mostly Tudor due to maintenance (Roman remains can be seen in and around the Tower of London). Other local remains are the 51.5169-0.095833 Noble St wall fragment and the 51.5177-0.092234 St Alphage Gdns wall fragment.

Founded by William the Conqueror in 1066, enlarged and modified by successive sovereigns, the Tower is today one of the world's most famous and spectacular fortresses and a UNESCO World Heritage Site. Discover its 900-year history as a royal palace and fortress, prison and place of execution, mint, arsenal, menagerie and jewel house. In the winter you can skate on the dry moat. The Tower contains enough buildings and exhibits to keep a family busy for a full day, with plenty of both warlike and domestic contents. Some areas, such as the St John's Chapel in the White Tower, do not allow photography, but these are clearly signposted. Beefeaters, who are all retired sergeant majors from the British Army, provide guided tours for free as well as ceremonial security. See history come alive – go to the Ceremony of the Keys at the Tower of London. This ceremony, the locking up of the Tower, has been performed every night at 10PM for 800 years. Tickets for the ceremony are £5 and must be prebooked.
