This is a unique museum located in a rocky area, called Rocky Compostela, which is part of the historic site of Portela de Villestro. The location is suitable for families with kids, making it a great option for a family outing. Unfortunately, the path to the site is not well-signaled, which made it difficult for us to find the location. Overall, this place offers a lot of interesting and educational content about ancient rock art and petroglyphs, which is a great experience for visitors. The fact that it's an open-air museum gives it a unique atmosphere. The combination of natural and cultural features makes it a must-visit destination for those interested in history and culture. However, the quality of the site could be improved with better maintenance and organization. The prices are reasonable and fit the quality of the experience. Despite some minor issues, the place has a lot of potential for growth and development, making it a great option for those looking for something new and exciting.
