The Carmelites were known as White Friars, were established in 1293 originally in Skirbeck, but later at a site off the High Street opposite Doughty Quay, which they bought from John Parleben in 1308, having been granted permission to erect a church by King Edward II. They bought more land in 1315/16. In 1349 Simon Lambert gave them more land, and a year later they received four acres from Sir John de Orreby.

The Dominican Friary
The Dominicans were known as Black Friars or Shod Friars. The Friary was founded in 1222. In 1288 their buildings, along with a large area of the town, were burnt during St Botolphs Fair, and in 1290 they were given eight oaks from Sherwood Forest by the King. In 1327 they were given a royal licence to build a subterranean aqueduct from Bolingbroke to their house. The friary was dissolved in 1539, and in 1540 the land was granted to the Duke of Suffolk. The refectory of the Dominican friary is the only part of any of the friaries still in existence. It is Grade II* listed, and houses the Blackfriars Arts Centre.

The Franciscans were known as the Grey Friars and their house was established at an unknown date prior to 1268. According to Leland, the Franciscans mixed with the Esterlings (European merchants), and many were buried there. Among those was Wisselus de Smallenburg, a merchant from Munster, who died in 1340, and whose grave slab today lies in St Botolph's Church, Boston. The friary was dissolved in 1539, and the site was first reserved for the King, but bought by the town in 1544/5.
