A road on the left at Lecarrow leads to a pleasant lakeside amenity area beyond which is the castle standing on a promontory projecting into the lake. When the Normans invaded Ireland, the eastern part of the country saw the building of many stone castles. They then crossed the Shannon and fortified themselves on the western bank. They built some mighty castles on the river banks, of which that at Rindoon are the most northerly. The castle is now an ivy-covered ruin, placed near the end of a peninsula stretching out into Lough Ree, and defended by a ditch which was cut through the width of the peninsula and filled with water (now dried up).
On the landward side is a church, and a cross-wall – the last surviving remains of a once-thriving medieval town, Rindoon, which was located on the green fields now peacefully grazed by cattle and sheep.
