St Mary's Guildhall is a major domestic complex, indicating the highest social status, built in the part of the medieval city of Lincoln, England, known as Wigford.

Stocker describes it as "the only survivor from the small group of the king's town houses which existed in several major towns….St Mary's Guildhall is a domestic complex on a palatial scale, indicating the highest social status, and as such is representative of a little known urban building type".

[2] In 1251 the building was sold by Henry III’s butler, Michael de la Burne, to the guild of St Mary of Lincoln.

He points out that the first floor great hall of the Guildhall, with its arcaded decoration, measures 20 m × 6.5 m, which makes it amongst the largest in a surviving building of the 12th century.

[14] However, the earlier ownership of Guildhall as constructed by Johnson does not fully fit this idea, even though the property was certainly owned by King Henry III.

[15] Johnson deduces that the property was originally owned by John de Holm (whose son, Adam was the first Mayor of Lincoln until 1216).

The King appears to have used the building for wine storage and then disposed of it to his butler, de la Burne in 1250, who almost immediately sold it to the Guild of St Mary in 1250/1.

One of the most useful sources of information for the history of the Guildhall are the ink-wash drawings of Samuel Hieronymous Grimm, a Swiss artist who was extensively employed by the Dean of Lincoln, Sir Richard Kaye, mainly to record architectural subjects.

The stone house closest to the church with the chimney, together with the bay with the porch next to the Guildhall, were demolished in 1896 to make way for Sibthorp Street.

Grimm also provides a detailed drawing of the main entrance showing the orders of the arch studded with flowers and dogtooth ornament and two heads on the door jamb, one of which is a bishop.

Although this building has two Romanesque windows and a massive pilaster on the front, it is in all probability an early 17th-century rebuild from the time that the Christ's Hospital Bluecoat School occupied the premises.

The exterior of the west range faces Lincoln High Street, The facade consists of five bays, has shallow buttresses, and a chamfered plinth and band of Romanesque decoration with bird and beast masks to the northern part.
