17-21, Parsonage Street

Nos 17 to 21 on Parsonage Street are a row of four shops built around 1820. They are constructed of Flemish bond red brick, which is mostly painted, with random rubble limestone at the rear. The buildings feature brick chimneys and roofs covered with Welsh slate and replacement tiles. They are three stories high with cellars, and there is an outshut at the rear of No 17.

The front of each shop has a single sash window arrangement, with 16-pane windows on the middle floor and 12-pane windows on the upper floor. Most windows have stone voussoir lintels, except for the upper floor of No 19, which has a plain concrete lintel instead. The shop fronts for Nos 17 and 19 were updated in the 20th century. Nos 19a and 21 feature late 19th-century canted bay windows, with grouped doorways in between.

The rear of the buildings has scattered segmental-arched windows. There is a flat-roofed 20th-century extension at No 17, which is not considered of special interest. This row represents the remaining half of a terrace that survived demolition for the construction of Castle Street.
