ARNSIDE, a hamlet, in the township and parish of Beetham, union and ward of Kendal, county of Westmorland, 4 miles (S. W.) from Milnthorpe. It is situated in the southern part of the parish, near the border of Lancashire, and at the point where the river Kent expands into the bay of Morecambe. The scenery is beautiful; the house of Woodclose, here, surrounded by 50 acres of land, is the residence of Robert Preston Rodick, Esq.; and Morecambe Cottage, that of his brother, Thomas Rodick, Jun., Esq. A curious cave was discovered in 1844; it has a narrow entrance, but contains several large chambers. Here, also, are the ruins of the Tower of Arnside, which is supposed to have been erected to command the bay.
