Grenhalgh Castle Ruins, Garstang

Thomas Stanley, 1st Earl of Derby, had the castle built in 1490 to provide defence for his estates around Garstang.

The land on which the castle was built is said to be a gift to Stanley from his stepson, Henry Tudor, for his assistance in defeating Richard III at the Battle of Bosworth Field.

Today, the only remain of the original four towers is the lower portion of one.

Many of the local farmhouses have incorporated the stones from the castle ruins into their buildings.
