The Santa Clara Battery was built on top of a hill which was home to one of the most historic caves on the island. The hill of Taganana, located in the coastal outcrop of Punta Brava near the cove of San Lázaro took its name from a cavern in the Canary Islands where the princess Guanche Cathaysa took refuge. She was captured and sold by the Castilians as a slave in 1494. The 7-year-old Guanche girl from Taganana (in Santa Cruz de Tenerife) was taken captive along with four other youngsters (Cathayta, Inopona, Cherohisa and Ithaisa). Cathayta was sold as a slave with her companions in Valencia, in April 1494. It is believed that after this she spent the rest of her life somewhere in Spain as a Menina for some woman of the Spanish high society. In Cuba, in a parallel legend that states that one of the caves under the Taganana hill served as a shelter for a Cuban Indian girl of the same name who fled from her Spanish persecutors. The Cuban novelist Cirilo Villaverde immortalized Guanche Cathaysa in his literary work, "La Cueva de Taganana".
