Allendale Library

Allendale Library is a chapel that has been converted into a library, dated 1878 above the porch. It is built of squared stone with raised ashlar quoins and dressings, and features moulded corbels at the eaves. The roof is made of fishscale slate, with coped gables that have kneelers and finials. The building is a single storey with five bays. The right bay has a gabled porch projection that includes a boarded door and a fanlight with intersecting glazing bars, all under a chamfered pointed arch. Above this, there are paired pointed windows with an inscribed panel reading 'PRIMITIVE METHODIST' along with the date. To the left, there are four pointed windows with intersecting glazing bars set in chamfered surrounds with hoodmoulds. The left return features two triplets of lancets under linked hoodmoulds, as well as a small pointed window in the gable.

Adjoining the north end of Allendale Library is a meeting room that was originally a chapel and later served as a Sunday School. This structure dates from the early 19th century, likely the first quarter. It is constructed of squared rubble with dressed door surrounds and window heads, topped with a concrete tile roof. Although it is a single cell structure, the street front gives the appearance of two storeys and has three bays. The ground floor features a pair of boarded doors flanked by 16-pane sash windows, with three additional 16-pane sashes above. The rear wall includes a 16-pane sash window to light the gallery on the left and a larger sash window on the right that lights the well of the chapel. The gable wall has projecting stones left for bonding into a future extension. The interior is a plain room without notable features, as the gallery has been removed and the roof structure is hidden by a modern suspended ceiling. Historically, this building served as the Primitive Methodist Chapel before a larger chapel was built next to it in 1878. This area was significant for Methodism in the 19th century, with many local adherents from the lead mines. Together, the two chapels form an important visual and historic group.
