The Clock Tower was built 1934-35 and stands at the corner of King St and St Andrews St and is a listed Category C building. It was designed by the architect William Forrest Valentine (1885-1957). The first tower, built by Sir William Douglas, was destroyed by fire in 1892 as was a second clock tower forty years later. A plaque records that in 1935 Henry J. Hewat of Paterson, New Jersey, USA, donated the present clock tower to the town. Capt Hewat was a native of Castle Douglas who had emigrated to the US in 1893.
