The cathedral site names 1181 as the year the present cathedral was begun. The building suffered considerable damage in 1648 and significant work in rebuilding was accomplished in 1862-1877 under the direction of Sir George Gilbert Scott. Find the cathedral website here. Information about the organ may be found here, sadly without a specification. Harrison & Harrison of Durham did the most recent work on the organ 1998-2000. The organ has a place on the National Pipe Organ Register, which thankfully does include the current specification.
