Place & story
A gateway between square towers
Samuel Lewis described the ruins at Rinduin in Saint John’s parish as including a defensive wall roughly five to six hundred yards long. An arched gateway stood near its middle, with square towers spaced about sixty to ninety yards apart. His measurements belong to an 1837 description of the surviving remains, rather than a current condition survey. [2]
Castle, church and burial ground
The castle occupied a rocky rise above Lough Ree, with a large courtyard and a strong keep. Lewis could not distinguish whether one projecting part had been a chapel or banqueting hall. He also recorded church remains dedicated to the Holy Trinity and a cemetery outside the wall still used in his time. The uncertainty about the castle room’s purpose should remain unresolved. [2]
