The map collection located in Christ Church Library and Archives is probably among the least known in Oxford. 

It includes such treasures as Martin  Llewellyn's 1598 Atlas of the East (a volume unknown to map  historians for over three and a half centuries, it constitutes the earliest sea atlas by an Englishman),  the 1612 Plan of the site of the Castle, showing Sellion’s House, the Jews’ Mount, houses in Castle Ditch and the West Gate of the City, Frederick Young's 1818 Plan of the Parish of Hawkhurst in the County of Kent (a masterpiece of cartographic art which also serves a practical role as a graphic inventory of land use) and Benjamin Badcock's 1829 Plan of estates in the University, City and Suburbs of Oxford belonging to Christ Church.

A masterpiece of cartographic art which also serves a practical role as a graphic inventory of land use. Unfortunately, the written survey which should accompany the map no longer survives.

Martin Llewellyn's Atlas of the East (1598)

Shelfmark: MS a.3 (West Table)
Manuscript charts on vellum. The earliest known sea atlas by a Brit and the earliest known British charts of the East. Given by Llewellyn’s sons to Christ Church in the 1630s, this remarkable atlas has yet to be systematically researched.
