History
The first evidence of human stationary presence in the current city is the settlement of Ametzagaña, between South Intxaurrondo and Astigarraga. The unearthed remains, such as knapped stones used as knives to cut animal skin, date from 24,000 to 22,000 BC. The open-air findings of the Upper Paleolithic have revealed that the settlers were modern human (Homo sapiens) hunters, besides pointing to a much colder climate at the time. There were Roman settlements (from around 50–200 AD) in what is now the Old Part of the city, according to excavations carried out in the convent of Santa Teresa, on the slopes of Urgull. San Sebastián is thought to have been in the territory of the Varduli tribe in the Roman times. east of the current city lay the Basque Roman town of Oiasso (Irun) which was subsequently incorrectly identified with San Sebastián for some time by many historians. No written records about the place are known until, in 1014, the monastery of Saint Sebastian with its apple orchards for cider production, then located within the boundaries of the town of Hernani, was reportedly donated to the Abbey of Leire by Sancho III of Iruñea. By 1181, the city was chartered (given the fuero) by king Sancho VI of Pamplona on the site of Izurum, having jurisdiction over all the territory between the rivers Oria and Bidasoa.

Perhaps as soon as 1204 (or earlier), the city nucleus at the foot of Urgull started to be populated with Gascon-speaking colonizers from Bayonne and beyond, who left an important imprint in the city's identity in the centuries to come. In 1265, the use of the city as a…

San Sebastián has three beaches, Concha, Ondarreta, and Zurriola, and is surrounded by hilly areas: Urgull (adjacent to the old part of the city), Mount Ulia (extending east to Pasaia), Mount Adarra (south of the city) and Igeldo (overlooking Concha Bay from the west). San Sebastián lies at the mouth of the Urumea river, and it was in large part built on the river's wetlands during the last two centuries. The city centre and the districts of Amara Berri and Riberas de Loiola lie on the former riverbed, which was diverted to its current canalized course in the first half of the 20th century. with warm summers and cool winters.
