Just to the north of the town is the wooded signal-beacon hill named Beacon Hill, but originally Penrith Fell. Its last use was probably in 1804 in the war against Napoleon. Traditionally, the Beacon Pike was used to warn of approaching danger from Scotland. Today, though surrounded by commercial woodland owned by Lowther Estates, the hill still has some natural woodlands and is visited by locals and tourists. On a clear day most of the Eden Valley, the local fells, Pennines and parts of the North Lakes can be seen. Beacon Hill may have given Penrith its Celtic name of "red hill".
