Description

The Portico, now serving as the entrance to the walled garden at Osborne House, dates from the 18th century. Originally, it was part of an earlier house that occupied the site of Osborne House. When Queen Victoria demolished the older house, the portico was relocated to its current position in 1848. The structure is finished in stucco and features rusticated pilasters that support a pediment. Within these pilasters is a rusticated archway, along with a door case that includes pilasters and a semi-circular fanlight. The portico is centrally located within a red brick wall that forms the eastern boundary of the walled garden. This wall has rusticated pilasters at regular intervals, topped with a modillion cornice and parapet that features ball finials.
