It has a brick Great House designed by David Adler in 1925 and built 1926-27, set within a formal landscape begun in 1910 by the Olmsted Brothers.","why_significant":"The nomination argues that Castle Hill is significant for its architecture, its landscape architecture, and its association with plumbing magnate Richard T. Crane, Jr. The house is considered David Adler's greatest work and one of the most significant early twentieth century houses in Massachusetts. The landscape combines designs by the Olmsted Brothers and Arthur Shurtleff.","narrative":"Castle Hill is a large seaside estate of about 165 acres east of Ipswich, Massachusetts, spread across three drumlins above the Atlantic. Its centerpiece is a two-story pink-red brick mansion designed by David Adler in 1925 and built in 1926-27. Adler drew on English houses such as Belton House and Eagle House, but combined their features into something largely original. Inside are a 63-foot gallery, a library with a carved mantel and panelling imported from Cassiobury Park in England, and bathrooms fitted with sterling silver and gold-plated fixtures. The surrounding formal landscape began in 1910 with the Olmsted Brothers and was extended by Arthur Shurtleff, adding the long allee to the sea, Italian gardens, a rose garden and a bowling green. The estate was built for Chicago plumbing manufacturer Richard T. Crane, Jr., and was left to the Trustees of Reservations in 1949. It is valued for its architecture, landscape design and Crane association.","period_of_significance":"1900-","architect_builder":"David Adler","architectural_style":"English transitional Elizabethan/English Renaissance, modeled on Belton House and Eagle House, with Queen Anne detailing","criteria":[],"status_note":"The house has been virtually unaltered since construction.
