The historic 19th-century, iron ore mining complex at the Roxbury Land Trust's Mine Hill Preserve is getting a sorely needed facelift this summer.

With help from a matching grant from the state, the land trust is working to stabilize stonewalls.

Work at the site, which is on the National Register of Historic Places, encompasses reconstruction of massive stonewalls in five areas, as well as much-needed drainage improvements.

To help underwrite the cost of the project, the land trust applied for and received a $43,000 grant from the state's Historic Restoration Fund, which is administered by the State Historic Preservation Office in the Department of Economic and Community Development.

"Mine Hill is one of Roxbury's and Connecticut's great historic treasures," said Steven Schinke, the land trust president. "We have always been committed to the ongoing stewardship of this site -- protecting its historic integrity and natural beauty and keeping it safe for our many annual visitors and school groups."

"We are grateful for the support of the state," he added, "and to our many donors who are making this preservation work possible."

Thomas Walker Construction of Woodbury was selected as the contractor for the rehabilitation work.

Mine Hill is open during the reconstruction project this summer but visitors are asked to exercise caution.

The Roxbury Land Trust purchased the 360-acre Mine Hill Preserve from the Matthews family in 1978.

It was designated a state and local National Register of Historic Places site a year later.
