[1] The area, visited by American and English sealers in the early 19th century, nowadays has become a popular tourist site frequented by Antarctic cruise ships.

The feature's name derives from 'Cecilias Straits' applied to English Strait by Captain John Davis after the shallop Cecilia, tender to his ship Huron that visited the South Shetlands in 1820–22.

It was from the Cecilia that the first landing on the Antarctic mainland was made at Hughes Bay on 7 February 1821.
