Ara Christi Charterhouse, El Puig, Renaissance monastery in El Puig, Spain.

Ara Christi Charterhouse is a Carthusian monastery in El Puig whose church was begun on 6 February 1621, with the first stone laid on 4 March, following the plan of Aula Dei. The complex was completed in 1641 and combines a Renaissance church with cloisters and monastic buildings.

Elena Roig, widow of Gaspar Artés, left her farm near El Puig to the Valldecrist charterhouse in her 1582 will, but a 1584 codicil redirected the bequest to a new foundation. On 7 April 1585 friars Sanxo Anyó, Joaquim Amigó and prior Miquel de Vera took possession before notary Joan Miquel. The order's general chapter confirmed the act that year and Archbishop Juan de Ribera in 1586. Construction of the new monastery began with the church in 1621.

The monastery displays Spanish Renaissance craftsmanship through its stonework and architectural details visible throughout the complex. The spaces were designed to serve both spiritual and everyday functions for those who lived here.

The charterhouse stands just outside El Puig de Santa Maria, near the Serra Calderona, and is now a private property run as a hotel, sports and leisure complex, so access follows the operator's conditions rather than those of a monument. Restoration work begun in 1999 has been controversial, so parts of the buildings may be closed off. Ask on arrival which areas can be visited.

The 1582 will of Elena Roig, widow of Gaspar Artés, first left her farm near El Puig to the Valldecrist charterhouse; a 1584 codicil, prompted by her confessor's dreams and her friend Isabel Joan Amigó, redirected it to the new foundation of Ara Christi. Her death followed on 1 April 1585.
