The Achbinico or San Blas Cave is a Catholic sanctuary located in the municipality of Candelaria, on the island of Tenerife.
It has great historical significance and archaeological importance for being the place where the Guanches, the first settlers of Tenerife, venerated the image of the Virgin of Candelaria before the European conquest, as well as for being the first Christian temple in the Güímar valley after the definitive incorporation of the island to the Crown of Castile at the end of the 15th century.
The cave-hermitage has been included since 2005 in the environment of protection of the Well of Cultural Interest of the Sanctuary of Candelaria.
This sanctuary is located at the end of the Paseo de San Blas, at the back of the Candelaria Basilica and under the coastal cliff of La Magdalena. The cave, which is hidden because a masonry building is attached to it, is long and deep, facing east. Its measurements are 14 meters long by 6 wide, and between 3 and 6 meters high.
