Ruins whisper tales of Cathcart Castle. Standing before its foundations you can almost feel the weight of history. This 15th-century castle in Linn Park held a prominent position. It was the seat of the powerful Cathcart family. They held the lands from the 12th century. The first Lord Cathcart’s elevation to the peerage around 1450 likely spurred its construction. The castle’s rectangular tower house measured 15.5 by 9 meters. It boasted five stories including a vaulted basement. A curtain wall with round corner towers and a twin-towered gatehouse enclosed a small barmkin. The tower house remains stand about 1 meter high today. Earthworks suggest an outer bailey or ringwork.
Archaeological digs unearthed a plaster armorial. It dates from the 1630s and shows the arms of Bryce Semple and Jean Lauder of Hatton. It was likely part of a fireplace overmantle. The Semple family acquired Cathcart Castle in 1546. They occupied it for roughly 200 years. The castle fell into disrepair. The Semples built Cathcart House nearby in 1740 and abandoned the castle.
The first Earl Cathcart reacquired his ancestral home in 1814. He planned to sell the stone rather than restore it. In 1866 the castle still stood five storeys tall. Surrounding outbuildings completed the complex. Glasgow City Council added the castle lands to Linn Park in 1927. The council demolished the dangerous ruins in 1980. Today only foundations remain a Scheduled Monument. Cathcart Castle’s story stands as a testament to a bygone era. A reminder of powerful families and the passage of time.
