 The original nucleus lies between the railway and the Ategorrieta Avenue, where still today the farmhouse Intxaurrondo Zar, declared "National Monument", is situated since the mid-17th century.The railway cuts across the district, the southern side being the fruit of the heavy development undergone in the area during the immigration years of the 1950s and 1960s.In addition, further housing estates have been built up more recently souther beyond the N-1 E-5 E-80 E-70 ring road (South Intxaurrondo).
