Bats patrol a palace library by night, eating the bookworms that threaten 36,000 leather-bound volumes.
The palace fills the horizon. Four hundred and forty rooms, 29 courtyards, a basilica modelled on St Peter's, and — at its heart — a Rococo library where six resident bat colonies eat the insects that would otherwise devour 36,000 leather-bound volumes. The bats are not a pest. They are the pest control.
The National Palace of Mafra is one of the largest royal residences in Europe, commissioned by King João V in 1717 and built over 13 years with a labour force that peaked at 45,000 workers. The palace-convent complex blends Baroque, Italianate, and Germanic influences, reflecting the wealth that poured from Brazil's gold mines. Its library — 83 metres long with marble floors — houses volumes dating to the 14th century, protected by bats that have roosted there for centuries. The six Anteros de Melo pipe organs, installed in the basilica in 1807, are the only known set of six organs designed to play simultaneously. José Saramago's 1982 novel *Baltasar and Blimunda* reimagines the palace's construction, adding a literary layer to the site's already considerable history.
Solo
Mafra demands a slow, detailed visit. Solo travellers can lose themselves in the library, the infirmary, the monks' pharmacy — rooms that reveal new details every time you look.
Couple
The sheer excess of Mafra is part of its charm. Wandering through 440 rooms together, trying to comprehend the ambition that built this place, makes for a day neither of you will forget.
Family
Children are fascinated by the bat-guarded library and the military museum within the palace. The surrounding tapada (royal park) offers deer-spotting and nature trails for when the architecture overwhelms younger visitors.
Friends
Mafra earns its place alongside Versailles and El Escorial — a palace so vast it takes a group to properly debate whether it is magnificent or mad. The answer, naturally, is both.
