[1] Wyke Castle was built around 1855 as a residence for Dr. Andrew Chadwick Fenoulhet, a local surgeon who came to Weymouth in 1842.

[7] It was advertised as a "unique, pleasant, and very healthy Gentleman's Residence, standing in its own Grounds, with Gardens, Conservatories, &c."[8] In 1899, the castle was under the occupation of Mr. P. Cruttwell of Frome, who used it as a holiday resort.

[10] Selous, a naturalist, author and traveler, decorated the inside of the castle's tower with his collection of butterflies.

During their time at the castle, Maxwell founded the local branch of the Women's Institute in 1923 and was its first president.
