The Archbishop's Palace is a Grade I listed historic 14th-century and 16th-century building on the east bank of the River Medway in Maidstone, Kent.

[2][3] At the end of the 14th century Archbishop Courtenay expanded the establishment in Maidstone when he founded the neighbouring College and Church of All Saints.

On the death of the third baron in 1688, the barony became extinct and the palace passed to his cousin Sir Jacob Astley.

[2] In 1720, Sir Jacob sold the palace to Robert Marsham, 1st Baron Romney who lived at nearby Mote House.

The roof is clay tiled and two projecting stone-built dormer windows at attic level on the entrance façade are capped with finials.

[3] Close to the palace on the south side is the dungeon, a 14th-century stone building with small windows and an early Norman undercroft.

[8] To the north-east of the palace, adjacent to Mill Street and the River Len is the 13th and 14th century gatehouse, a two-storey building constructed of roughly-coursed rubble and timber framing on the east end.
