Description

The obelisk, urns, and seat located approximately 100 meters to the south-west of Penn House is a monument built between 1733 and 1744 for Alexander Pope in memory of his mother. The urns are attributed to William Kent. Constructed from ashlar, the obelisk consists of stone slabs. The obelisk and two urns are arranged in a triangular formation, with a low stone curved bench on brick piers positioned between the urns. Each of the tall obelisk and urns features a stepped base, a plinth with a moulded base and cornice, while the urns are decorated with a spiral pattern and topped with conical finials.

Pope originally erected the monument at his house in Twickenham, known as Pope's Villa, in memory of his mother who passed away in 1733. The monument was relocated to its current site around 1830.
