Where to stay in Diagonal Mar
The practical side of choosing where to sleep.
The seafront is the point of staying in Diagonal Mar, with the Pavelló de la Mar Bella and Port Fòrum Sant Adrià both on the same stretch of water. Museu Blau sits close. Sant Martí carries on behind it, and the older streets of Poblenou begin a short way from the water.
Visitors who want the sea within a walk get it here; visitors who want the Barcelona of narrow streets will be travelling in each day, which is the trade this neighbourhood asks.

About Diagonal Mar
What are the main landmarks in Diagonal Mar?
Museums come first here. The Museu Blau and the Natural Science Museum of Barcelona both appear on the record, and MUHBA Oliva Artés stands among them with the name of Poblenou attached. Two memorials sit apart from the rest: the Parapet dels executats and Bosc d'empremtes (Memorial del Camp de la Bota).
Monument a la Sardana and Monument a Camarón de la Isla stand outdoors, while Casa Josep Blasi and Casa Emili Bossa keep two house names in the list.
What is the history of Diagonal Mar?
Diagonal Mar comes to the list undated. What the record holds instead are parish and house names, Santa Maria del Taulat i Sant Bernat Calvó, Sant Paulí de Nola, Casa Josep Blasi and Casa Emili Bossa, that tie this ground to Poblenou and to the wider Sant Martí district of Barcelona. The Església del Sagrat Cor de Jesús belongs to the same layer.
The full name on the register is Diagonal Mar i el Front Marítim del Poblenou, and it is what appears on maps of Catalonia.
Where is Diagonal Mar?
The shore runs along one side. Port Fòrum Sant Adrià and the Pavelló de la Mar Bella mark the water's edge, with Poblenou inland of Diagonal Mar.
