[3] On 23 January 1954, Argentine Navy personnel inaugurated the Capitán Cobbett Naval Refuge on a rocky promontory on Primavera Cape, along the southwestern coast of Cierva Cove in the north access to the Gerlache Strait.

[3] Lieutenant Colonel Ignacio Carro and eight men under his command expanded the Capitán Cobbett refuge, setting up all the facilities needed to support the Argentine Antarctic Institute–commissioned scientists.

[3] As of 2014[update] Primavera is only inhabited during summer, and has 11 buildings for housing a maximum of 18 people,[1][4] a crew usually made up by a staff of 6 Argentine scientists, 4 invited foreign ones and 7 army personnel.

Some of the base's critical facilities are the main house, dining room, heliport, infirmary, power plant, vehicle fleet, laboratory, workshop (mechanical, carpentry) and deposits.

[3] Some of the scientific research programs locally carried out include limnology, ornithology, study of mosses and lichen species and their ecological impact.
