There is a privately held manor house,
Westover House, on a hill overlooking Calbourne. The Westover Estate was established during the reign of
Edward the Confessor. Westover House was once owned by Colonel Moulton-Barrett. Colonel Mouton-Barrett was a relative of the poet
Elizabeth Barrett. Calbourne is also close to the site of
Swainston Manor, which is a mile to the east of Calbourne. Now a hotel, Swainston Manor was originally a manor house on a site dating back to 735 CE. Eight hundred years ago it became the location of a palace built by the Bishops of Winchester. It has a 12th-century chapel on its . Most of the present building was constructed in the 18th century, but an attached hall dates from the 13th century.
Warwick the Kingmaker reportedly dined at Swainston Manor. Calbourne is the location of Winkle Street, a picturesque row of cottages which frequently appears on photographs and postcards of the
Isle of Wight. Winkle Street looks out on the village stream. Winkle Street was originally named Barrington Row, presumably after longtime residents of
Swainston, the Barrington family.
All Saints' Church, in the centre of Calbourne, was established in 826. It features a brass portrait of an armoured knight with hands folded in prayer, resting his feet on a dog. The pictured knight is thought to be William Montacure who was
Earl of Salisbury and a governor of the island in the 14th century. Legend has it that Montacure was killed when he was jousting with his father. The heartbroken father created altar tombs in every church in every village in which he owned land or houses.
John Buckler, a British artist and architect, was born in Calbourne. ==Today==
