At the top of the hill at the north end of the Grand Avenue approach to Stowe from Buckingham, The Corinthian Arch was built in 1767 to provide the main entrance to the house and the estate, and to convince visitors they were entering one of the very best of such estates. The south front of Stowe house is visible through the arch. The arch contains two houses and has windows in the side elevations. The pair of flanking milestone columns were added by 1780. This is not now the main entrance to the estate which is along the Oxford Avenue approach to the west.
