Plaza de toros de Acho, Historic bullring in Rímac, Peru.

The Plaza de Toros de Acho is a bullring in the Rímac district of Lima, built of adobe and wood. Its pale tan outer cylinder is pierced by tall narrow openings between pilasters, and a colonnade of thin red pillars carries a shallow roof above the upper concourse. Inside, concentric rows of seating step down to a 60-metre ring.

The arena was founded in 1766, making it one of the oldest bullrings built in South America. It has remained operational since its opening, reflecting Spanish colonial architectural traditions from that era.

For locals, this is a place where traditional Spanish-style bullfighting remains a living practice and cultural expression. The venue connects Lima's residents to their colonial past through events that continue to draw crowds who value this artistic tradition.

The ring has 15 seating sections, or tendidos: 2 to 7 lie in the shade, 9 to 15 in the sun, and 1 and 8 get both. The Patio de Sombra on the west side holds the Bullfighting Museum and a restaurant. The bullfighting fair runs on Sundays through October and November, so time a visit outside those months for the quieter courtyards.

Since 2006 the plaza has belonged to the Unión de Plazas de Toros Históricas, founded by the Amigos de la Plaza de Toros de Béjar together with the mayors of Campofrío, Santa Cruz de Mudela and Almadén and the Real Federación Taurina de España. It is the only bullring in the Americas visited by King Juan Carlos I of Spain.
