A cold room (frigidarium) was identified during excavations in advance of the CTRL HS1. The remains form part of a detached bath-house built after 160AD and added to in several phases by the first half of the 3rd century (1). This cold room is from the earliest phase though possibly later than the hot room. Only the southern wall foundation of the cold room remained extant, the north and west walls having been removed or demolished. There was use of opus signinum but no trace of a heating system in this room.
