Founding of the city

1541 founding of Santiago
Santiago was founded by Italy/Spanish Conquistador Pedro de Valdivia on February 11, 1541 with the name Santiago de Nueva Extremadura, as a homage to Saint James and Extremadura, Valdivia's birth place in Spain.[1] The founding ceremony was held on Huelén Hill (later renamed Cerro Santa Lucía). Valdivia chose the location of Santiago because of its climate, abundant vegetation and the ease with which it could be defended—the Mapocho River then split into two branches and rejoined further downstream, forming an island.[2] The Inca ruler Manco Cápac II warned the new rulers that his people would be hostile to the occupiers. The Spanish invaders had to battle against hunger caused by this resistance. Pedro de Valdivia ultimately succeeded in stabilizing the food supply and other resources needed for Santiago to thrive.[3]
The layout of the new town consisted of straight roads of 12 varas (14.35 m, 47.1 ft) width, in equal intervals of 138 varas (165.08 m, 541.6 ft) perpendicular to each other. With nine roads in the east-west direction and 15 in the north-south direction, there were 126 blocks that formed the so-called manzanas, or square cut.[4
