Situated some 60m North of the remaining structure of Old Henllan. On North boundary of site.

Circa 18 garden arch in red brick with round-headed recessed arch. Each face of the outer arch with moulded brick imposts to pier and remains of moulded brick plinth. Keyblock under crown of each outer arch. Remains of raised stringcourse above. Possibly broken for centre plaque.

A rare survival of early brickwork in this area. In 1891 the gateway was said to have the White family coat of arms and date "171 "(broken). this may survive under ivy. The Whites owned the estate from circa 1545; in 1670 it passed to the infant Elizabeth. Later Lady Bulkeley (d 1736). But after her first marriage circa 1677 the house was let; the estate eventually was joined to the Stackpole estate.
