Castle Hill is a series of buildings used as council offices in Winchester, Hampshire, England.

The complex was originally designed by Owen Browne Carter[3] in the Elizabethan style and completed in 1833.

[4] The Castle Hill Offices were rebuilt to a design by James Robinson and Sir Arthur Blomfield in 1895.

[1] The design, which was completed in flint and Bath stone, involved an asymmetrical main frontage on the east side of Castle Avenue; the central section featured two large oriel windows on the left and a tower and a round headed doorway on the right.

Queen Elizabeth II Court, a large red-brick rectangular building with a clock tower and a central courtyard, was built to the north of Castle Hill on the opposite side of Upper High Street and was completed in 1960.
