The Head Office and Garden of the Calouste Gulbenkian Foundation are easily visitable from the nearby metro station: São Sebastião. Arriving mid-evening, numerous locals were enjoying this green space with blanket spreads, picnics, or just people lying down on the beautiful grounds. 

The garden is pleasant indeed, with bamboo, a trickling brook that dissects the grounds (plenty of turtles, ducks), and modern statues surrounded by green foliage. This was a highlight for me since we had spent several hours exploring Lisbon (2 days) during the morning, evening, and night (often quite busy). Therefore, this little slice of green mixed with modern architecture was a breath of fresh air.

Certainly, the use of concrete and glass here stands out. In some ways, the greenery has enveloped the large modernist structures, creating a unique interaction of the man-made and natural components.
