From Case’s-tower on the walls of the city, at the end of Fishamble-street stood a castle, that in different ages bore two names, viz. Proutefort's-castle, and Fyan's-castle, probably from some families of both those names, who either built or inhabited it. William Proutefort was a man of some figure in the reign of Edward III. and was appointed one of the commissioners (Rot. Tur. Birm. 32 Edw. III. No. 3.) for levying a subsidy granted by the communities of the counties of Cork, Limerick, Tipperary and Kerry to Almarick de Sancto Amando, lord justice, for carrying on the war against the Irish enemies an. 1358.
