It was charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and named by the sixth Chilean Antarctic Expedition (1952) for Lieutenant Ladislao D'Hainaut.

The refuge with its current name, which pays tribute to the Argentine naval Captain and historian Teodoro Caillet Bois, was given in December 1977 by the icebreaker ARA General San Martin (Q-4).

Then it was closed and evacuated on 17 January of the following year by the icebreaker personnel.

[citation needed] The ARA Petty Officer Castillo visited the shelter in early 2000 during the Antarctic campaign of 1999-2000 and the ARA Almirante Irizar inspected the refuge in April of the same year.

The refuge was renovated in March 2017 by the personnel of the transport ARA Bahía San Blas.
