Very beautiful, but be careful: paths can flood at high tide. You'll then have to stand in knee-deep water for a few meters with your bike.

Although the construction history of this impressive church in Gloria (Aveiro) dates back to the 15th century – and thus to the beginning of the "golden" Age of Discovery – it is a relatively young cathedral. Originally a monastery church, it belonged to the convent of the local Dominican Order. The memory of this is still alive today in the patronage. However, it has only served as the cathedral (Se) of the relatively young Diocese of Aveiro for less than 100 years.
