Merlo

The town sits at 796 meters elevation in the Comechingones Sierra and records mild temperatures plus clear skies during most of the year. The built-up area spreads along several streets that wind between hills and valleys.

The settlement started in 1794 after Juan de Videla recognized the potential of the Piedra Blanca area and became formally established in 1796. The following decades brought further settlements into the valleys of the sierra.

The Chapel of Nuestra Señora del Rosario in La Villa Colonial ranks among the oldest church buildings in the country and holds the status of national monument. Its simple design still shows the features of early colonial architecture.

Valle del Conlara Airport sits 18 kilometers from the center and links the town with several major Argentine cities through regular domestic flights. Streets in the built-up area lead to different viewpoints and walking trails in the surrounding hills.

The ancient tree El Algarrobo Abuelo stretches its five massive branches across the landscape and marks more than a thousand years of natural history. Its trunk reaches a girth that several people standing together could embrace.
