"It is known that several of the de la Poles sought burial in the
Charterhouse (which effectively became the family’s northern
mausoleum). Sir William de la Pole (died 1366) and his wife Katherine
(died 1381) were buried beneath the high altar in the priory church
and their son Michael, 1st Earl of Suffolk and his wife Katherine in
the chancel." So says John Cook, writing in 1882. What happened to the graves of such an illustrious family?
The priory was closed in 1539. Writing in the early 1540s, John Leland reported (in his Itineraries),"The Charter House of the De la Poles foundation, and an Hospital of
their Foundation standing by it, is without the North Gate. The
Hospital standeth. Certain of the De la Poles were buried in this
Carthusian Monastery: and at the late suppressing of it were found
divers troughs of Lead with Bones in a Vault under the High Altar
there. Most part of this Monastery was builded with Brick, as the
Residue of the Buildings of Hull for the most part be." [spelling modernised] The lead coffins indicate high status burials. But what happened to these coffins? No one knows.
Carthusians have always buried their own dead without coffins, usually in the cloister garth. This is consistent with what was found in the early 19th century, when the land which once belonged to the Priory was developed into what is now Sykes Street. On 3 June 1809 the Hull Advertiser reported that human skeletons had been found, oriented east - west, and that "masses of wall of immense thickness" were discovered when digging for the foundations of new houses. The skeletons were no doubt those of the monks who had lived and died in the Priory. But, like the aristocratic remains found many years before, they appear to have been discarded. Archaeology had not yet developed as a science, and no plans were made of the site. Perhaps before any future redevelopment of the area there will be an attempt to excavate it properly.
