Castletroy is a suburb of Limerick, Ireland. The town was named after Castle Troy also known as the Black Castle, which is located on the southern bank of the River Shannon, roughly 2 km east of the University of Limerick. However the name likely predates the castle itself as the area may have been used by the O’Turrain clan having used it as a safe harbour for navigating the river.

Annacotty is a small village on the outskirts of Limerick, Ireland, 7 km (4 mi) from the centre of the city. It is situated where the old N7 main road between Limerick and Dublin crosses the Mulkear River, 1 km (0.6 mi) upstream of where it flows into the River Shannon.
