Greenfield Valley Heritage & Country Park is a 1½ mile-long linear
park following the course of the Holywell Stream between the town
and the estuary of the River Dee, and through which the most steeply
graded conventional standard gauge railway in the UK once ran.
Here,
in addition to St Winefride's Holy Well and 12th century
Basingwerk Abbey, lie the remains of a number of historic
mill buildings, many of which are by now scheduled ancient
monuments.
More recently,
cottages, farmhouses and even a Victorian school have been moved
here stone by stone from other locations and carefully reconstructed
and furnished as they might have been in centuries gone by.
