The Vidago Palace Spa, in Trás-os-Montes, is worth visiting for the wide range of effective facial and body treatments, together with Aromatherapy Associates & Clarins, but also for the surrounding areas and architecture. The building, in a minimalist style, with straight lines and white marble, was designed by Álvaro Siza Vieira and contrasts with the Belle Époque opulence of the main hotel building.
