The Corinium Museum holds one of Britain's great Roman archaeological collections and a wide pre-historic and social history collection of local and national interest. The collection has a particular emphasis on the town of Cirencester and the South Cotswolds. The wealth of Cirencester from the middle ages to the eighteenth century was based on the wool trade. Many rich wool merchants lived in Cirencester and their influence can be seen in much of the town's beautiful architecture. They built expensive houses (the museum is situated in one) and their wealth contributed to the exquisite church and its unique South Porch, used as the Town Hall, now being restored with the help of National Lottery Heritage funding. One of these great wool merchants was John Coxwell (1516–1618) who was born in Cirencester. He profited from the dissolution of the great abbey in Cirencester, purchasing considerable property from Queen Elizabeth 1st to add to his estate in other parts of Gloucestershire. His town house was in Abbott Street, now called Coxwell Street, and was probably Woolgatherers. In 1614, at the age of 98, John Coxwell commissioned Cornelis Janssens van Ceulen to paint his portrait. In 2002 the painting was donated to the museum by Colonel Coxwell-Rogers, a descendant of John Coxwell.
