LeCarrow is a village in County Roscommon located approximately 17 kilometers north-west of Athlone Town. A canal connects it to Lough Rae, the second largest lake on the River Shannon. It is the closest population located to the geographical centre of Ireland.

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.

On the landward side is a church, and a cross-wall – the last surviving remains of a once-thriving medieval town, Rindoon.
