Feria de Chillán, Street market in Chillán, Chile

Feria de Chillán, also called Feria Artesanal de Chillán or Feria de la Plaza Sargento Aldea, is a commercial enclosure in the centre of Chillán where stalls fill the square once known as La Merced. Its first structure dates from 1997, and in 2017 a roof was built over the Arturo Prat street entrance. Vendors sell basketry, wicker and blankets from Quinchamalí, Coihueco, Minas del Prado and Pinto, alongside typical food of the Ñuble Region.

The area around Plaza Sargento Aldea was held by government forces during the 1813 Battle of Maipón in Chile's War of Independence. After the 1835 earthquake the city was rebuilt on its present site, with a square called La Merced laid out here. In 1858 the municipal market, "La Recova", moved to the square's north side; when traders outgrew it they set up stalls in the square itself, creating the fair. The first permanent structure dates from 1997, and the Arturo Prat street entrance roof was added in 2017.

Artisans display pottery from Quinchamalí featuring black clay with white geometric patterns, representing traditional Chilean craftsmanship still made by hand in the region. These ceramics are widely purchased by visitors seeking genuine local pieces.

The fair occupies Plaza Sargento Aldea, with its main access on Arturo Prat street, covered by a roof built in 2017. The first structure of the current building dates from 1997. The surrounding streets are laid out around the square, so the stalls can be reached on foot from the centre of Chillán.

The fair grew out of the Mercado Municipal, known as "La Recova", which moved in 1858 to the north side of the Plaza La Merced; when its stalls overflowed, traders spread onto the square itself. Sections were then set aside, first for Quinchamalí pottery, later for Fanaloza earthenware from Penco and textiles from Bellavista Oveja Tomé. The first permanent structure dates from 1997, and the roof over the Arturo Prat entrance was added in 2017.
