Duckett's Grove is the ruins of the 18th to early 20th-century home of the Duckett family, which was formerly at the centre of a 12,000-acre (49 km2) estate, that has dominated the landscape of Carlow for over 300 years. Duckett's Grove was built in 1830 by William Duckett in a Castellated Gothic revival style. The building incorporates numerous towers and turrets of varying shapes – round, square and octagonal. Following the departure of the Ducketts the castle was destroyed by fire in April 1933 but the cause of the fire has never been determined.
