Cobh, known from 1850 until the late 1920s as Queenstown, is a tourist seaport town on the south coast of County Cork, Ireland. Cobh is on the south side of Great Island in Cork Harbour and is home to Ireland's only dedicated cruise terminal. Tourism in the area draws on the maritime and emigration legacy of the town - including its association with the RMS Titanic.
Whilst under the Post Office of Great Britain the town of Queenstown was allocated the numeral cancel 157 in 1849 (NB from 1844-1849 this number had been allocated to the town of Cove-Ireland).
