The monument is the remains of Newark Castle. It is visible as a 15th century tower house and gatehouse linked by later 16th century ranges arranged around a central courtyard. The monument situated on the south bank of the River Clyde at about 5m above sea-level. 

The scheduled area is irregular on plan to include the remains described above and an area around in which evidence for the monument's construction, use and abandonment is expected to survive, as shown in red on the accompanying map.  The scheduling specifically excludes: the above-ground elements of all modern boundary walls and modern fences; the slipway; the above-ground elements of all signage and services; the top 300mm of all modern paths to allow for their maintenance.

Statement of National Importance

The monument is of national importance because it has an inherent potential to make a significant contribution to our understanding of the development of Scottish castles during the late-medieval and early-modern periods. The monument survives as a roofed structure, with rare and important original timber work. It is an excellent example of its type demonstrating the transition from a medieval castle to a mansion house. It documents through its architecture and layout the economic and social changes following the Union of the Crowns which allowed a greater degree of peace and prosperity for Scotland's land-owing class. Previous excavation has indicated high potential for the survival of important archaeological remains. The loss of the monument would greatly diminish our ability to understand the character, chronology and development of late-medieval and early-modern high-status dwellings in Scotland.

About Scheduled Monuments

Historic Environment Scotland is responsible for designating sites and places at the national level. These designations are Scheduled monuments, Listed buildings, Inventory of gardens and designed landscapes and Inventory of historic battlefields.

We make recommendations to the Scottish Government about historic marine protected areas, and the Scottish Ministers decide whether to designate.

Scheduling is the process that identifies, designates and provides statutory protection for monuments and archaeological sites of national importance as set out in the Ancient Monuments and Archaeological Areas Act 1979.

We schedule sites and monuments that are found to be of national importance using the selection guidance published in Designation Policy and Selection Guidance (2019)

Scheduled monument records provide an indication of the national importance of the scheduled monument which has been identified by the description and map. The description and map showing the scheduled area is the legal part of the scheduling. The statement of national importance and additional information provided are supplementary. These records are not definitive historical or archaeological accounts or a complete description of the monument(s).

The format of scheduled monument records has changed over time. Earlier records will usually be brief. Some information will not have been recorded and the map will not be to current standards. Even if what is described and what is mapped has changed, the monument is still scheduled.

Scheduled monument consent is required to carry out certain work, including repairs, to scheduled monuments. Applications for scheduled monument consent are made to us. We are happy to discuss your proposals with you before you apply and we do not charge for advice or consent. More information about consent and how to apply for it can be found on our website at
