The castle on the hill above Santa Cruz (to the north) gets its name from the five-yearly festival where they bring the statue of the Virgin Mary down from Las Nieves into Santa Cruz. It’s not much used in between fiestas, but Wednesday 20th April is The World Night in Defence of Starlight, and Astrotour will be holding a Star Party there from 9 pm to 1 am.
You’ll be able to see Saturn and its rings through a telescope, watch an audiovisual presentation, and see the main constellations.
The castle is one of La Palma’s network of viewpoints recommended for stargazing, and will be named after Spica, the brightest star in the constellation Virgo. Even though it’s so close to the town, you can still see the brighter stars, thanks to La Palma’s Sky Law. It should be an interesting night.
