The Castle of Lagos, also known as the Castelo dos Governadores was built in Roman times and was renovated and enlarged during the 16th century, providing the town with its main defence against intruders. In 1755 it was practically destroyed by the tsunami that followed the great earthquake and once it was reconstructed it was officially recognised as a National Monument.
Today, the well-preserved portion of the city walls and towers, guard the entry archway and are well worth a visit and offer some lovely photo opportunities. There is a café in the castle grounds, offering a variety of delicious meals and snacks, all at reasonable prices. Or if you prefer, the park in front of the castle is a lovely spot for a picnic or just to sit and relax and take in the view of the ocean in front of you.
