This pub is located in the north corner of St. Samson's Square, nearest the Minster, just south of the site of the porta principia sinistra, the south-eastern gateway of the Roman legionary fortress, which was discovered in 1854 beneath King's Square along with the important inscription RIB 665. The pub is remarkable because during excavation of the site the caldarium or 'hot room' of a Roman legionary bath-house was discovered. This building was originally erected close inside the south-eastern defenses of the Roman fortress, possibly sometime during the early second century AD.
