Original: Ye Olde Trip To Jerusalem, partially built into the cave system beneath Nottingham Castle, is a contender for the title of "England's Oldest Pub" due to its supposed establishment in 1189. The Bell Inn on the Old Market Square, and Ye Olde Salutation Inn on Maid Marian Way, have both disputed this claim.
Simplified: The contender are Ye Olde Trip To Jerusalem near the castle, The Bell on the Old Market Square, and The Salutation on Maid Marian Way.
