Plummer Tower

Plummer Tower is a Grade I listed town wall tower, which was later used as a Company Meeting Hall and is now offices. It dates from the late 13th century to early 14th century and was refronted around 1740, with a house added in the late 18th century. The tower is constructed of coursed and squared sandstone, featuring an ashlar front and returns, topped with a Welsh slate roof.

The structure is semi-circular with a Palladian style front that has two storeys and one wide bay. There are two steps leading up to a boarded door with a two-pane overlight set in a keyed architrave. The flanking windows also have similar architraves, and the ground floor features rustication that forms voussoirs. A band on the first floor supports end pilasters and a central plinth for a high Venetian window in the Doric Order, which is adorned with a triglyph frieze and block rustication on the central arch. All windows are sashes with wide glazing bars. The top entablature has a pulvinated frieze and a dentilled cornice, culminating in a high coped parapet and a hipped roof.

On the right return, there is a door with a three-pane overlight at first floor level, set in a rusticated surround with a cornice. The later house on the left is built in English garden wall bond with a Welsh slate roof, featuring two storeys and two bays. A central door has been bricked up and has a wedge stone lintel, while a renewed door has been inserted to the right in a stone surround. The windows flanking the blocked door and the first floor windows all have wedge lintels and projecting stone sills, and are sashes with glazing bars. A small rectangular window at the centre of the first floor has a header course sill and lintel.

To the right of the tower, there is a wall with high-sloped coping that shelters a walkway at the first floor level of the tower. There are side stone steps in front, and a stone platform around the steps features cast iron principals with urn finials and plain wrought iron railings. Plummer Tower is also a scheduled ancient monument.
