When the Condor attacked, the residents of Guernica tried to protect the tree with their bodies because it is sacred to the Basques. Even today, elected politicians have to swear their loyalty to the Basque Country at an oak tree that stands a few meters away.

The legend that attributes the name of Mundaca to the Latin expression munda aqua (clean water). This legend appears in the Chronicle of Vizcaya written by Lope García de Salazar in the 15th century. According to this story, a ship from Scotland arrived on the coast of Mundaca carrying a princess who had been banished from her land. The Scots called the place Munda aqua in their Latin language (sic) since they found a very clean source of water that contrasted with the murky waters of the Urdaibai estuary.

A low point on the tour. It was a Sunday and all the restaurants were packed. When I politely expressed my wish to be able to charge the battery in Spanish, we were literally thrown out. Spaniards drive long distances to eat out on Sundays. It has never happened to us that the battery was not allowed to be charged. Of course we would have eaten and drank. The whole place was almost entirely made up of holiday apartments, with the blinds down and totally dead without the lunch guests. No hotel, no guesthouse, but with a train station. Cheers to the Euskotren regional train in the Basque Country, on time, super helpful staff. So take the train back to Gernica!!!

Urdaibai Bay is an important coastal biotope. The Spanish advertising advertises the region as a cycling region, ok without luggage and mountain bikes perhaps

Completely destroyed by the German Condor Legion in the Spanish Civil War. https://de.wikipedia.org/wiki/Luftkampf_auf_Guernica A well-worth seeing exhibition in the central square shows the horrors of the civil war. The Spanish spelling with "ue" probably goes back to Picasso.
