Ondarroa is a fishing and canning port. At the top of town, the church of Santa María and the Likona Tower are its chief characteristics.
To the east of Ondarroa, the beach of Saturraran marks the boundary of the coast of Vizcaya with that of Guipuzcoa. The historic quarter is one of its prettiest places. It has an unmistakably medieval and seafaring atmosphere, with steep, narrow streets. Here you will find the Likona Tower, from the 15th century, a typical border structure. Standing nearby is the marvellous church of Santa María (1462) built on the rock. The old City Hall, which is another place of interest, has a Tuscan façade very different to the rest of the buildings in town.
