The Knock of Alves is a small wooded hill that lies 3 miles (4.8 km) to the west of Elgin in Moray, Scotland, rising to 335 feet (102 m) above ordnance datum.

[1] Its summit is marked by York Tower, a 3-storey octagonal folly erected in 1827 to commemorate Prince Frederick, the Duke of York; and the Forteath Mausoleum, built in 1850 as the burial place of 7 members of the Forteath family of the nearby house of Newton.

It is traditionally believed that there was an early Christian church, possibly Culdean, on top of the hill, though no traces of this have been found.

[5] These are characterised as massively constructed oblong forts, commonly exhibiting evidence of vitrification.

[5] The remains of the fort are now heavily mutilated and defaced and have been damaged by the building of the tower and mausoleum; by erosion from the provision of access roads; by root damage, animal burrowing and slope wash.[6] The fort was surveyed by the Royal Commission on the Ancient and Historical Monuments of Scotland in 1957.
