Elsdon Tower : Description of The North Wall
The entrance to the Tower is set a little east of centre on the north side, and is now covered by a 19th century vestibule or lobby. The doorway is now quite a wide round-headed arch, with a continuous broad hollow chamfer, but it is formed entirely in plaster, and carries various heraldic shields; its original form is uncertain.
Above the roof of the present porch is a plain lancet-shaped window lighting the newel stair; this and two similar ones above look to be of late 18th or early 19th-century date. Between the upper two is a blocked square-headed loop, formed simply out of four stones, its jambs inclining inwards towards the top. This looks an original feature; its present situation, midway between two turns of the present stair, suggests there have been internal alterations (see below).
Above the roof of the lobby, but below the string course, are a pair of square-headed windows with recessed and chamfered surrounds; they have ashlar dressings, and look to be of mid or late 19th century date.
Immediately above the string course, and set west of centre, is a blocked square-headed window with a chamfered surround, partly hidden by the roof of the adjacent wing. There has been a similar window above and a little to the west; the chamfered jambs are original but the head and sill are recent restoration.
Below the parapet (and breaking its chamfered base course), positioned directly above the entrance door, is a machicolated projection set on four corbels, between which fire could be directed or objects dropped on unwelcome visitors attempting to gain admission.
The parapet of the tower (but not of the machicolated projection) has clearly been heightened, except for a small section at each end; the heightened sections have a 'battlement' of triangular-section blocks. There is a slightly-raised section above the projection, containing a square panel with the arms of the Howards of Overacre.
The section of the external face of the north wall seen within the roof space of the vestibule seems to have been rendered or harled, in the manner of many Scottish towers. It may be worthwhile removing samples of this render for analysis.
