The monument consists of the remains of Gilbertfield, also called Gilbertfiled castle, a seventeenth century L-shaped mansion situated on the lower slopes of Dechmont Hill.

The remaining structure is rectangular, the SE wing having been demolished. The four-storey house is aligned N-S and measures 14.6m by 8.5m over walls 0.9m thick. The walls are complete to wallhead (10m) although they are showing signs of decay. There are two crowstepped gables intact to a height of 17m, one in the N wall and one in the S end of the W wall. In the NW angle there is a corbelled turret. The masonry is coursed sandstone bonded with lime mortar. The entrance is in the E angle. The lobby is partly rubble filled as a result of the collapse of the stairs. This passage leads to the main newel stairwell. The rooms in the ground floor were all vaulted but only that over the N cellar is intact. The kitchen was in the demolished SE wing. The dining room took up the S portion of the

first floor and was connected to the kitchen by a service stair in the SW wall. The N parlour is accessible through a corridor that runs parallel to the main staircase. There were three bedrooms in each of the two upper floors. Large windows light the S, W and E sides, two of which have decorative gun-holes in their sills. The main staircase has several smaller windows.

The area to be scheduled is square with sides measuring a maximum of 30m to include the mansion, as shown in red on the accompanying map.

Statement of National Importance

The monument is of national importance as a particularly good example of a dwelling house which illustrates the transition between defensive keep and the modern mansion house. It is therefore important both architecturally and historically.



RCAHMS records the monument as NS65NE 12.

About Scheduled Monuments

Historic Environment Scotland is responsible for the designation of buildings, monuments, gardens and designed landscapes and historic battlefields. We also advise Scottish Ministers on the designation of historic marine protected areas.

Scheduling is the way that a monument or archaeological site of national importance is recognised by law through the Ancient Monuments and Archaeological Areas Act 1979.

We schedule sites and monuments of national importance using the criteria published in the Historic Environment Scotland Policy Statement.

The description and map showing the scheduled area is the legal part of the scheduling. The additional information in the scheduled monument record gives an indication of the national importance of the monument(s). It is not a definitive account or a complete description of the monument(s). The format of scheduled monument records has changed over time. Earlier records will usually be brief and some information will not have been recorded. 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
