• Closes at sunset, so winter afternoon visits are short and summer evenings run late
• Birds by the lake: mallards, plus kingfishers and night herons on the garden's own species guide
• Family workshops run through the year (building nest boxes, for one), listed on the garden agenda

A modernist garden designed in the 1960s by landscape architects Gonçalo Ribeiro Telles and António Viana Barreto around the Calouste Gulbenkian Foundation buildings. Wooded paths open onto small lawns and a central lake where mallards swim and kingfishers and night herons turn up.

Kids can follow the trails, watch the ducks from the pebble shore on the south bank, and explore the open-air amphitheater.
