Templemichael Castle stands north of Rincrew in County Waterford, built by the FitzGerald family in the 16th century at the confluence of the Glendine River and the Blackwater. Some sources suggest the site dates to the 12th century as a Knights Templar stronghold. The ruined structure retains portions of two walls and shows evidence of original architectural features including vaults, a large garderobe chute and spiral stairs, though much was demolished by gunpowder in antiquity. The castle sits within a parish bounded by the navigable Blackwater River, forming part of the region's rich tapestry of medieval fortifications in the barony of Coshmore and Coshbride.
