Fiestas

St Sebastian: 19 January
Our Lady of Costitx: 4 September
Costitx is said to be the very centre of the Island and the place where the air is least polluted which is why it was chosen as the site for the Observatory in 1991.

It has been populated since prehistoric times and stones still stand at the nearby Talayot Age sanctuary at Son Corró. This was where the three large bronze bulls heads were found in 1895. These are now housed in the Spanish National Archaeological Museum in Madrid and loaned to Mallorca on special occasions

It is also the location of the Costitx Natural Sciences Museum, with several hundred showcases covering ichthyology, herpetology, ornithology, and entomology, in addition to over one thousand species of butterflies and 500 species of fungus, seventy-five percent of which are native to the Balearic islands. Open Tuesday to Friday from 09.30 to 01.30.
