Holy Trinity Priory, Aldgate

The house was founded with clergy from St Botolph's Priory in Colchester,[4][5] and the first prior was Norman, who was the queen's confessor.

[3] By 1115 the entire soke, or liberty of East Smithfield (including the ward of Portsoken) was given by the Knighten Guilde to the church of Holy Trinity within Aldgate.

[7] In the 12th century the priory had a reputation as a centre of learning under Prior Peter of Cornwall.

However this authority was disputed by Holy Trinity, and after a lawsuit before arbitrators appointed by Pope Honorius III the matter was referred to the bishop of London, who decided in 1223 that Holy Trinity should be free from visitation from the canons and priors of St Botolph's.

[8] Thomas Pomerey is named as the prior of the house & church of Holy Trinity within Algate, in 1460.
