Cenobio de Valerón on Gran Canaria, Spain

One of the most interesting archaeological sites in all of Europe is Cenobio de Valerón, which is located on the Spanish island of Gran Canaria. The island is situated on Africa's northwest coast. The island is even more alluring as a location for exploring historical monuments since it has so much to offer in terms of history, ecology, and weather. A complex network of ancient caves is known as the Cenobio de Valerón, also referred to as the Caves of Valeron or the Monastery of Valeron. The caves are situated directly on the cliff in the Municipality of Santa Maria de Guia in the northern part of the island.

It is, in essence, the greatest collective pre-Hispanic granary (with 298 compartments and 350 storage places). Actually, it was constructed before the Roman era. But until the island was taken in the late 15th century, the locals of the islands continued to use the caves. These caverns' enormous size only serves to highlight the historical significance of the island's agriculture.
