Rumicolca, Pre-Columbian archaeological site in Lucre District, Peru

Rumicolca is a stone gate and aqueduct on the Cusco–Puno road, 31 km southeast of Cusco near Pikillaqta and Lake Huacarpay. Its core is rough Wari masonry, faced with finely cut and polished Inca stone. A canal runs along the top of the structure, and the inner faces of the gate carry protruding knobs.

Rumicolca was probably built in the Tiahuanaco-Huari period and later faced with finely cut and polished stones during Inca rule. The Inca also used it as a control post on the Cusco–Puno road. Much of the structure consists of rough Wari stonework encased in Inca veneer.

The name derives from Quechua rumi (stone) and qullqa (deposit or storehouse). Local Cusco folklore tells of a Wari leader who offered his daughter's hand to whoever could bring water to Pikillaqta; the man from Cusco built the canal and aqueduct now called La Portada de Rumicolca. On the inner sides of the gate, carved stone knobs appear, which Víctor Angles interpreted as a form of ideographic writing.

Rumicolca lies 31 km southeast of Cusco, beside the Cusco–Puno road and near Pikillaqta. The site is an open-air structure with no facilities, so bring water and sun protection. The altitude is high, so allow time to acclimatise before walking around.

The paleohydrologist Kenneth Wright concluded that the canal running along Rumicolca was part of the original Wari structure, not a later addition. On the inner sides of the gate, carved stone knobs appear that also occur at Pisac; Victor Angles interpreted them as a form of ideographic writing.
