The Lee Baths in Cork were open air swimming pools that operated from 1934 to August 10th, 1986. I have absolutely no memory of the place but others do. Check this thread or this thread on PROC and this blog post for some excellent commentary
My father [Andy O’Brien] ran the Lee Baths with military precision and the place was spotless. He was a well known sporting figure in Cork in the Thirties because of his prowess as a high board diver wining many cups and medals for high board and spring board diving at local and national diving championships in Ireland. Diving as a sport was quite popular in Europe in particular in Germany. My father loved the outdoor life and learned to swim himself. He had a natural ability. Apart from the Eglinton Baths there was a swimming area in the River Lee near the Lee Waterworks weir (just up from Kingsley Hotel)before the 1934 Lee Baths opened . The steps are still there.
