The Alcobaça Monastery
Founded in 1153 and built in stages over more than a century, the Mosteiro de Santa Maria de Alcobaça is the first example of Gothic architecture in Portugal, a unique landmark that had no immediate successors. The great nave, 106 metres long in the largest church in Portugal, is of a breathtaking Cistercian purity: soaring columns of pale limestone, no colour, no ornament, nothing to distract the eye or mind from the vertical ascent toward the vault and the light filtering through plain windows. It is architecture that achieves its effect through proportion, silence, and stone alone - and the effect is overwhelming.
