The Palacio Salvo rises above the southeast corner of Plaza Independencia in a fantastical eclectic style — part Art Deco, part neo-Gothic, topped by a lighthouse tower. It was built by the Salvo family between 1922 and 1928 and served as a combined hotel, apartment building, and commercial complex. The design by Italian architect Mario Palanti is genuinely strange: the building narrows as it rises, with turrets and ornamental detail that belongs more to a fairy-tale castle than an office block.
The building is now divided into private apartments and offices, but the lobby and lower floors can be visited. Guided tours are available and go up to the tower for views over the Río de la Plata. At night the facade is lit up, and the building is particularly striking from the far end of the plaza.
