Dean Castle Country Park in Kilmarnock, Ayrshire, stands as one of the region's top free visitor attractions, formerly serving as the home of the Boyd family for over 400 years. Originally called Kilmarnock Castle and renamed to reflect its wooded valley setting, the castle was reduced to ruins by a devastating 1735 fire before undergoing extensive restoration by the 8th Lord Howard de Walden, completing the Keep by 1908 and Palace by 1930. The venue houses nationally significant collections including 15th–16th century European arms and armour, 16th-century Brussels tapestries, and rare musical instruments dating to 1570, while visitors can explore multiple chambers including the Keep, Great Hall, Solar, and Banqueting Hall.
