This ‘Eleanor Cross’ was erected by Lord Breadalbane in 1831 as a tribute to his wife Mary, Countess of Breadalbane. Built on the site of an old summer house known as Maxwell's House on the north bank of the River Tay, it stands 30 feet high and has a 9 step octagonal bottom that encircles the building,  a cruciform middle stage and a square pinnacle top stage surmounted by cross.  A heavy door of chlonte-slate, of which the monument is built, opens to a spiral staircase, which leads to a small arched gallery running round the structure, open to the exterior.  On a brass mural tablet there is the following inscription:

This Building is Dedicated to my Faithful Friend and Fellow-Labourer,
MARY, COUNTESS OF BREADALBANE,
Whose maternal care has been long extended to all around this place.
anno domini, 1831.
