About Las Condes

Las Condes is an affluent commune in northeastern Santiago, Chile, known as the country's main financial hub and one of Latin America's most prosperous urban districts. It concentrates corporate headquarters, luxury hotels, and high-rise offices in a sleek skyline locals call "Sanhattan"—a nod to its blend of Santiago and Manhattan. Beyond its business core, Las Condes is home to exclusive residential neighborhoods, top-ranked schools, and a cosmopolitan mix of international institutions and communities.
