Nature One of Europe's tallest Douglas fir trees can be found in the fir plantation in Tolosa. History A 9000-year-old human settlement was discovered in the neighbourhood of San Esteban. From the tools and remains of flint carvings found, it would be a group whose economy was based on hunting and fruit gathering. From the Bronze Age, about 4000 years old, are the dolmens of Belabieta and Añi, burial constructions that bear witness to the first religious manifestations. In the Iron Age, about 2300 years ago, the first settlements appear. They settled on medium-high mountains, such as Intxur in Aldaba, and protected themselves by surrounding themselves with walls. In addition to their knowledge of iron, they were farmers and ranchers. The whole of antiquity, including Romanization and until at least 1025, when Gipuzkoa entered history, is an obscure period about which little is known. The territory of Gipuzkoa was incorporated to Castile in 1200. In 1256, King Alfonso X the Wise of Castile granted the charter to Tolosa, naming it after Toulouse, France. In this charter, the inhabitants of Tolosa were granted privileges that were not granted to the inhabitants of nearby villages, nor to those of other provinces. It also provided for the fortification of Tolosa, Ordizia and Segura, border points with Navarre.
