London Mithraeum

Londinium, also known as Roman London, was the capital of Roman Britain during most of the period of Roman rule. It was originally a settlement established on the current site of the City of London around AD 47–50. It sat at a key crossing point over the River Thames which turned the city into a road nexus and major port, serving as a major commercial centre in Roman Britain until its abandonment during the 5th century. Following the foundation of the town in the mid-1st century, early Londinium occupied the relatively small area of 1.4 km2 (0.5 sq mi), roughly half the area of the modern City of London and equivalent to the size of present-day Hyde Park. In the year 60 or 61, the rebellion of the Iceni under Boudica compelled the Roman forces to abandon the settlement, which was then razed. Following the defeat of Boudica by the Roman governor Gaius Suetonius Paulinus a military installation was established and the city was rebuilt. It had probably largely recovered within about a decade. During the later decades of the 1st century, Londinium expanded rapidly, becoming Britannia's largest city, and it was provided with large public buildings such as a forum and amphitheatre. By the turn of the century, Londinium had grown to perhaps 30,000 or 60,000 people, almost certainly replacing Camulodunum (Colchester) as the provincial capital, and by the mid-2nd century Londinium was at its height. Its forum-basilica was one of the largest structures north of the Alps when the Emperor Hadrian visited Londinium in 122. Excavations have discovered evidence of a major fire that destroyed much of the city shortly thereafter, but the city was again rebuilt. By the second half of the 2nd century, Londinium appears to have shrunk in both size and population. Although Londinium remained important for the rest of the Roman period, no further expansion resulted. Londinium supported a smaller but stable settlement population as archaeologists have found that much of the city after this date was covered in dark earth—the by-product of urban household waste, manure, ceramic tile, and non-farm debris of settlement occupation, which accumulated relatively undisturbed for centuries. Some time between 190 and 225, the Romans built a defensive wall around the landward side of the city. The London Wall survived for another 1,600 years and broadly defined the perimeter of the old City of London.

Bloomberg London is an office building in London, which was opened in 2017. It is owned by Bloomberg L.P. and functions as their European headquarters. It is at 3 Queen Victoria Street, to the west of Walbrook, on the site previously occupied by Bucklersbury House.

Walbrook is a City ward and a minor street in its vicinity. The ward is named after a river of the same name. The ward of Walbrook contains two of the City's most notable landmarks: the Bank of England and the Mansion House. The street runs between Cannon Street and Bank junction, though vehicular traffic can only access it via Bucklersbury, a nearby side-road off Queen Victoria Street.

St Stephen Walbrook is a church in the City of London, part of the Church of England's Diocese of London. The present domed building was erected to the designs of Sir Christopher Wren following the destruction of its medieval predecessor in the Great Fire of London in 1666. It is located in Walbrook, next to the Mansion House, and near to Bank and Monument Underground stations.

The Walbrook Club is a social and business dining club near the Bank of England and the Mansion House located in the Ward of Walbrook in London. The Club is set in a Queen Anne-style townhouse at the end of a private court next door to the UK offices of Rothschild's, the Church of St Stephen's, and opposite the Bloomberg European Headquarters. There is a bar, a dining room, and two smaller private rooms.

No 1 Poultry is a building in the City of London, allocated to office and commercial use. It occupies the apex where the eastern ends of Poultry and Queen Victoria Street meet at Mansion House Street, the western approach to Bank junction. The design, by James Stirling, was constructed after the architect's death. It replaced a neogothic, conical-turretted, predecessor retail building, owned by developer Rudolph Palumbo and subsequently by his son, developer Peter Palumbo. Another option was a modernist minor skyscraper designed by Ludwig Mies van der Rohe in the manner of the Seagram Building in New York City – but dropped having failed in an influential architectural and planning show-down in the 1970s. The tall but less towering design, in a postmodernist style with an outer shell of even bands of rose-pink and muted yellow stone, prevailed. The point of the apex, as before, has a clock face but higher, as above a large pointed apex set of 30 window panes. In 2016, the landowner proposed exterior alteration. Building users, experts and neighbours persuaded the experts at the designated UK body to protect and recognise the building and did so in the notable grade II* listed building category, making it, within England, the youngest at the time. The rooftop restaurant was used for the apparent Queen's helicopter departure point in the 2012 Summer Olympics opening ceremony.

St Benet Sherehog, additionally dedicated to St Osyth, was a medieval parish church built before the year 1111, on a site now occupied by No 1 Poultry in Cordwainer Ward, in what was then the wool-dealing district of the City of London. A shere hog is a castrated ram after its first shearing.

The Steelyard, from the Middle Low German Stalhof, was the main trading base (kontor) of the Hanseatic League in London during the 15th and 16th centuries.

Poultry Compter (also known as Poultry Counter) was a small prison that stood at Poultry, part of Cheapside in the City of London. The compter was used to lock up minor criminals and prisoners convicted under civil law and was run by the City's Sheriff. It operated from the 16th century until 1815. It was pulled down in 1817 and replaced with a chapel.

Poultry (formerly also Poultrey) is a short street in the City of London, which is the historic nucleus and modern financial centre of London. It is an eastern continuation of Cheapside, between Old Jewry and Mansion House Street, towards Bank junction.

Stocks Market was a market in central London operating between 1282 and 1737 and for centuries was London's main retail meat and produce market. The market was located to the east of the Walbrook in the heart of the City of London. It was demolished to make way for the building of the Mansion House on the same site.

St Mary Colechurch was a parish church in the City of London destroyed in the Great Fire of London in 1666 and not rebuilt.
