1. Admire artefacts at the Gallery of Royal Collections
What is it? A museum space showcasing the artistic heritage of the Spanish monarchies, until now displayed in the National Heritage warehouses and the Royal Sites.
Why go? Aside from the architectural beauty of the building itself, the Gallery offers the chance to view some previously unseen works or pieces commonly found in palaces and monasteries outside of Madrid.
Don’t miss: The building is organised downwards, so start at the top. On the first level, you’ll encounter paintings, jewellery, sculptures, and other Habsburgs items. A level below you’ll find artifacts related to the Bourbons. Plus there’s a room housing a significant archaeological discovery unearthed during construction, as well as another room dedicated to temporary exhibitions.
