The building of the National Palace of Ajuda didn't get built without its share of troubles. The structure you see today isn't the original. The palace was originally planned as a summer residence in the first half of the 18th century by King John V, but construction would only begin after Paço da Ribeira, the royal residence in the centre of Lisbon, was destroyed by an earthquake in 1755.

The first Palace of Ajuda was made from wood, but burned down in 1794. Then, the much more fire-proof building you see today was constructed. To this day, ceremonies for the Republic and the presidency are held in the palace.
