Glassonby is a small village and civil parish in the Eden Valley, in the Westmorland and Furness district of Cumbria, England.

The original village of Addingham and its parish church stood on the eastern bank of the River Eden, in the north-western corner of the Glassonby township.

Addingham village appears to have been abandoned sometime between the 14th and 16th centuries, and the old parish church and its graveyard were gradually washed away by the changing course of the river.

To the west of the stones were 32 deposits of burnt bones, with accompanying Beaker ware cups, fragments of urns and 12 shale beads.

Two of the decorated stones, along with incense cups and flint instruments found at the site, are on display at the Tullie House Museum and Art Gallery in Carlisle.

[11][12] The civil parish of Glassonby stretches from the banks of the River Eden to the summits of the North Pennines, where it borders Alston Moor.

In addition to Glassonby itself it includes the village of Gamblesby, a separate civil parish until 1934, and the hamlets of Glassonbybeck, Maughanby and Unthank.

Private Robert Beatham VC, an Australian soldier and posthumous Victoria Cross recipient, was born in Glassonby.

He emigrated to Australia as a teenager, prior to the outbreak of the First World War and was killed in action on 9 August 1918, aged 24.
