Min y Don Hall was situated next to the Park. Formerly Colwyn Farm, this was built in the 1700s and occupied by the Clough family, descendants of Sir Richard Clough who married Catherine Tudor, a ward of Elizabeth I.
Enhanced over the years, the completed mansion had over 30 rooms. In the 1820s Sir Richard Butler Clough imported coal to a yard near the shore and made Beach Rd into a trade route by narrowing the river and building a retaining wall. Vehicles using the road were charged sixpence (2.5p). A mill in Beach Road ground the abundant local gorse for horse feed. Charles Frost, a later owner, built a mission hall at Bryn y Maen and his widow, Eleanor, financed the building of the church there in 1897. In 1899 she also laid the foundation stone at St John the Baptist in Old Colwyn and gave the chancel’s fittings.
The Hall was a preparatory school from the early 1900s until 1937 when, along with part of the estate, it was sold to a local builder for housing development.
It was demolished in 1938.
In 1926 the Council was offered a field next to Min y Don Hall for a public park if the community raised £1,000 towards the cost. The park opened in 1928.
