Clare Castle Country Park was transferred from Suffolk County Council to Clare Town Council in March 2015. It was created around the ruins of Clare Castle and incorporates the now defunct Clare railway station on the Colchester to Cambridge branch of the Great Eastern Railway.
It is managed on behalf of the Town Council by the Clare Castle Country Park Trust. Their website has details of their work. plans and aspirations, the park’s history, heritage and ecology and much more: events, volunteer programme, photo gallery.
The park was opened in June 1972, after 15 acres (6.1 ha) were donated by Anthony de Fontblanque and 4.5 acres (1.8 ha) of railway land bought for £10,000. In 2014 the keep and curtain wall were extensively consolidated with the assistance of English Heritage (now Historic England – see their listing). On the keep two of the surviving merlons have been refaced and capped; a walkway has been reintroduced – all to protect the surviving original masonry. A flagpole was fixed to the outer wall; for most of the year, a flag is flown: the chevron of Clare.
