The Sant Serni de Llorts Church is part of the parish of Ordino. The current building has Baroque architecture and was built to replace an ancient temple that is thought to date back to Roman times.
The church has been declared of cultural interest and has a rectangular main floor, where there is an altarpiece dedicated to Sant Serni and Christ. The façade faces south and overlooks a small square. On top of that, it has a central door that is surrounded by an arch and a pumice stone frame. One of the most characteristic features of the church is the double bell tower that presides over the main façade.
