Templehouse Lake

Overview

Templehouse Lake (Irish: Loch Templaig) lies on the southern edge of County Sligo, about a 20‑minute drive from Sligo town. The 200‑acre freshwater lake forms part of the Owenmore River’s course, stretching roughly 2 km north‑to‑south and 500 m east‑to‑west. Its clear, hard‑water surface is dotted with a series of crannogs – artificial islands dating back to the Iron Age – and is surrounded by the pastoral landscape of the Templehouse demesne.

History & Background

The lake’s story is inseparable from the wider Templehouse estate. The earliest recorded structure on the shore is a rectangular, keepless hall‑house built around the late 13th century (first mentioned in 1271 when it was “broken down by Hugh O’Connor”). IrishHistory.com describes the surviving ruins as a two‑storey limestone building, 22 m × 12 m, with a distinctive sloping batter at its base – a hallmark of medieval Irish hall‑houses rather than a Knights Templar foundation.

Later medieval alterations added segmental vaulting across the ground floor and four ground‑level window embrasures. An early medieval high‑cross base within the ruins hints at pre‑13th‑century religious activity. The estate passed to the Knights Templar in 1216, then to the Knights Hospitaller after the Templars’ suppression, before being acquired by the Perceval family in the 17th century. The present Georgian manor, reconstructed around 1825, overlooks the lake and the medieval ruins, creating a striking juxtaposition of architectural eras.

The lake supports a modest but diverse fishery – roach, perch, pike, bream, rudd, hybrids and the critically endangered European eel – and provides wintering grounds for ducks such as teal, wigeon and goldeneye, as well as waders like lapwing, curlew and the rare Greenland white‑fronted goose. It is protected under the Templehouse and Cloonacleigha Loughs Special Area of Conservation (SAC).

Wildlife Highlights

Birdwatchers will find Templehouse Lake rewarding year‑round. In winter, flocks of teal, mallard and tufted duck glide across the surface, while mute swans and great crested grebes nest along the reed‑lined margins. Recent records (April 2026) on BirdGuides show occasional rare visitors such as Bridled Tern, Hoopoe, Ferruginous Duck, Black‑crowned Night Heron and Lesser Yellowlegs, making the lake a point of interest for serious birders.

Activities

Water Sports

The estate’s boathouse, operated by Wild Wet Adventures, offers a range of water‑sport sessions (advance booking recommended):

All sessions include safety equipment and a brief instruction from qualified guides. The calm lake is ideal for beginners and experienced paddlers alike.

Rowing Boats

Estate residents may use the rowing boats free of charge; visitors can arrange a short hire through the boathouse. Rowing provides a gentle way to glide past the crannogs, medieval ruins and Georgian manor – perfect for photography.

Angling

Coarse fishing on Templehouse Lake is free and available year‑round. Anglers must hold a valid Irish fishing licence and observe the ban on live bait for pike. Species regularly caught include pike, perch, roach, bream, rudd, hybrids and eel. No day‑rate is charged (Infowing confirms fishing is free).

Walking & Exploration

A short, well‑marked footpath runs along the lake’s northern shore (approximately 2 km), allowing visitors to admire the crannogs up close and view the medieval castle ruins. The trail is suitable for most walkers, though some sections are uneven and may be challenging for wheelchair users. An early medieval high‑cross base near the castle adds an extra point of interest for history enthusiasts.

Birdwatching

The lake’s SAC status means visitors are asked to keep noise to a minimum and avoid disturbing nesting birds. A pair of binoculars and a field guide will enhance the experience, especially during the winter months when rare migrants have been recorded.
