Calouste Gulbenkian Museum in Lisbon

You're standing at the Calouste Gulbenkian Museum, on Avenida de Berna in Lisbon. Have a look around. There's no grand palace here, just a long, low, understated building, half tucked away in greenery. That's entirely deliberate. The building and the park were designed together, with terraces and pools of water that blur the line between concrete and nature.
