Thomas Ross, in his first Guide to Hastings, 1835, from 6, Castle Street, says of this part : "The Town of St. Mary's" is now rapidly springing up between the "towns of Hastings and St. Leonards " ; already some well-built houses, such as Verulam-buildings, Seymour Place, Adelaide Place, etc., have been erected.
The grounds are also laid out for a square (Warrior Square). The South Saxon Hotel is the only one at present in the place; and the grand promenade, which joins that of St. Leonards, forming the "finest parade in the Kingdom.". Brett says :- "Mr. Troup, who built Warrior Square, proposed that the new town between the Archway, St. Leonards (Mr. Burton's boundary) and the Seaside Hotel (now the Palace) should be called "St. Marys."
