Westminster Abbey is a large, mainly Gothic church, in Westminster, London, located just to the west of the Palace of Westminster. It is the traditional place of coronation and burial site for English, later British and later still monarchs of the Commonwealth Realms. According to a tradition first reported by Sulcard in about 1080, the Abbey was first founded in the time of Mellitus, Bishop of London, on the present site, then known as Thorn Ey (Thorn Island). The Abbey's two western towers were built between 1722 and 1745 by Nicholas Hawksmoor, constructed from Portland stone to an early example of a Gothic Revival design. The bells at the Abbey were overhauled in 1971. The two service bells and the 1320 bell, along with a fourth small silver "dish bell", kept in the refectory, have been noted as being of historical importance by the Church Buildings Council of the Church of England.

The Palace of Westminster, also known as the Houses of Parliament, is the meeting place of the two houses of the Parliament of the United Kingdom—the House of Lords and the House of Commons. It lies on the north bank of the River Thames in the heart of the London borough of the City of Westminster. Its Clock Tower, in particular, which has become known as "Big Ben" after its main bell, is an iconic landmark of London and the United Kingdom in general, one of the most popular tourist attractions in the city and an emblem of parliamentary democracy. Big Ben is the largest four-faced chiming clock and the third-tallest free-standing clock tower in the world. It celebrated its 150th anniversary in May 2009, during which celebratory events took place. The Palace of Westminster has been a Grade I listed building since 1970 and part of a UNESCO World Heritage Site since 1987.

Portcullis House is an office building in Westminster, London, UK, that was commissioned in 1992 to provide offices for 210 Members of Parliament and their staff, augmenting limited space in the Palace of Westminster and surroundings. The building was designed by Michael Hopkins and Partners and incorporates Westminster tube station below it. The building's curious profile, with its rows of tall chimneys, is intended to recall the Victorian Gothic design of the Palace of Westminster and to fit in with the chimneys of the Norman Shaw Building next door. The building itself is created to look and feel like a ship inside. All the offices and passages are made up with bowed windows and light oak finishing. Each floor looks identical to the others except the ground floor which houses the main courtyard with ship-like metallic sails suspended overhead. The courtyard is decorated with trees and two shallow baths of water.

On Pall Mall to the North of St James Park, you will find St James Royal Palace, which is one of the oldest working palaces in the capital.

The palace was commissioned in 1536 by King Henry VIII and is still an official residence of the monarchy, even though no king or queen has lived there since 1837, when Queen Victoria made Buckingham Palace her official London residence.

The palace was built on the site of a sanatorium for lepers, dedicated to St James, hence the name of the palace. Built in the Tudor style of red brick, the palace has four courtyards and a gatehouse at its North end. The gatehouse is one of the few parts of the building that date back to Tudor times, along with a couple of rooms and the Chapel Royal. The main part of the palace was destroyed by fire in 1809, during the reign of King George III.

King Charles I was born there but during the Commonwealth Period, Oliver Cromwell had the place transformed into a prison and barracks. King Charles II restored the palace in 1680 and his brother James II lived there during his short reign as king.

Queen Victoria and Prince Albert were married in the Chapel Royal, which is open to the public. The heart and bowels of Queen Mary I are buried in the chapel. In front of the gatehouse you can have your photo taken next to the Guard from the Household Division.

Buckingham Palace is the official London residence of the British monarch. Located in the City of Westminster, the palace is a setting for state occasions and royal hospitality. It has been a rallying point for the British people at times of national rejoicing and crisis. Originally known as Buckingham House, the building which forms the core of today's palace was a large townhouse built for the Duke of Buckingham in 1703 on a site which had been in private ownership for at least 150 years. It was subsequently acquired by George III in 1761 as a private residence for Queen Charlotte, and known as "The Queen's House". During the 19th century it was enlarged, principally by architects John Nash and Edward Blore, forming three wings around a central courtyard. Buckingham Palace finally became the official royal palace of the British monarch on the accession of Queen Victoria in 1837. The Buckingham Palace Garden is the largest private garden in London.
