Description
The lamp post outside 1 Dean Trench Street is a gas street light that features an ornate column, likely dating from the late 19th century, with a Grosvenor-type lantern that was probably installed around 1930.
The lamp post is made of cast iron and includes a glazed lantern constructed from iron, spun copper, and enamelled aluminium. The decorative fret surrounding the top of the lantern is likely made of cast lead.
The design of the lamp post includes a column with acanthus leaves at the base and floral mouldings, topped with the Grosvenor lantern. The square tapered base of the column has an oval plaque with the number 8014. There are two ladder bars on the column. The lantern itself is circular, featuring tapered and curved glazing panels held by metal glazing bars. It is topped with a decorative, perforated fret and an ogee finial. Inside the lantern, there is a six-mantle inverted burner, a Horstmann 14 day clockwork time controller, and a steel reflector. The lantern is mounted on a four-legged frog that is attached to the collar of the column.
