Santa Cruz de La Palma was the 6th town in the world to have electric streetlights, starting in 1894. It wasn’t some noble idea of progress: the shopkeepers in the centre of town got together and arranged the lighting in order to extend the shopping day. The lights were powered by a hydro-electric plant outside town.
Most lights on La Palma are designed to send all the light downwards, where you want it, and none upwards to annoy astronomers. However, a few of the original C19th streetlights have been kept outside the Town Hall, and there’s a plaque.
