The Canary island of La Palma (ancient Benahoare) is one the richest island territory of the world in rock art manifestations (Martín Rodríguez and Pais Pais, 1996); there are dozens of petroglyph stations in a territory of only 700 km2 . These groups of petroglyphs, carved in a delicate way by picking or lining techniques, often are

Along the first millennium BCE and up to the beginning of the Roman conquest at the end of III century BCE, the southeast part of the Iberian Peninsula was colonized by Phoenicians, Greeks and Punics. All these cultures influenced the religious and funereal world of the indigenous peoples. Tartessians and Iberians were the main Protohistoric

The work presented in this article is part of a wide-ranging and ambitious project, started few years ago, to study the role of astronomy in Roman urban layout. In particular, the main aim is to check whether Roman cities present astronomical patterns in their orientations. The project emerged from ideas on how to properly orientate the main

The Observatorio del Roque de los Muchachos (ORM), in the Canary Islands (Spain), was one of the candidates to host the future European Extremely Large Telescope (E-ELT) and is the site of the Gran Telescopio Canarias (GTC), the largest optical infrared facility to date. Sky transparency is a key parameter as it defines the quality of the

Over 30 years of solar data have been acquired by the Birmingham Solar Oscillations Network (BiSON), an international network of telescopes used to study oscillations of the Sun. Five of the six BiSON telescopes are located at major observatories. The observational sites are, in order of increasing longitude: Mount Wilson (Hale) Observatory (MWO)

The MAGIC telescopes in La Palma, Canary Islands, measure the Cherenkov light emitted by gamma ray-induced extended air showers in the atmosphere. The good knowledge of the atmospheric parameters is important, both for the correct and safe operations of the telescopes, but also for subsequent data analysis. A weather station measures the state
