Enric Sagnier i Villavecchia (Catalan pronunciation: [ənˈrik səŋniˈe]; 1858 in Barcelona – 1931) was a Catalan architect.
Although now not as well known as his contemporaries Antoni Gaudí, Lluís Domènech i Montaner and Josep Puig i Cadafalch, he was responsible for a number of landmark buildings, was very prolific, and could turn his hand to many styles, including neo-Gothic, neo-Baroque and Modernista. He qualified as an architect in 1882, and one of his earliest works, together with Josep Domènech i Estapà, was the Palau de Justícia in Barcelona.
Other well-known buildings by him in Barcelona are the Caixa de Pensions building in the Via Laietana, the New Customs House (Duana) and the church on the Tibidabo.
Enric Sagnier was born in Barcelona on 21 March 1858, the son of Lluís Sagnier i Nadal, president of the Caixa d’Estalvis i Mont de Pietat de Barcelona (a bank), and Clementina Villavecchia Busquets. His father was an outstanding Classics scholar, who translated Xenophon and Anacreon, and the young Enric was a talented painter and violinist. He studied at the Barcelona Higher School of Architecture, from which he graduated in 1882.
He began his professional career as an assistant to Francisco de Paula del Villar y Lozano: under his instructions he carried out his first work, the refurbishment of the chapel of Sant Josep in the church of Santa Maria de Montserrat abbey (1884). His first important work was the church of Santa Engràcia de Montcada (1886), in neo-Gothic style; it was destroyed during the Spanish Civil War. His first apartment building, the Casa Cuyàs, was built the same year.
