Basílica de San Judas Tadeo, El Santuario, Gothic Revival church in El Santuario, Colombia.

The Basílica de San Judas Tadeo in El Santuario is a three-aisled neo-Gothic church measuring 56 m long and 20.60 m wide. Its central nave rises 12.85 m under a flat ceiling, the side aisles reach 9 m, and the tower stands 38 m tall. The carved image of Saint Jude Thaddeus on the main altar came from Barcelona in 1899.

The Diocese of Medellín authorized construction on 11 May 1898, and the first stone was laid on 28 October, the feast of Saint Jude Thaddeus. Work stalled and was revived in 1911, when a two-slope roof replaced the original single-slope one. The exterior was finished in 1935 and the church consecrated on 24 August; the tower was reinforced after the 1962 earthquake, and in 2017 Pope Francis raised it to a minor basilica.

The basilica is dedicated to Saint Jude Thaddeus, a figure venerated in Catholic tradition for hope and difficult causes. Religious artworks displayed inside reflect the community's spiritual devotion and connection to this patron saint.

The church is centrally located in El Santuario, making it easily accessible for visitors. Appropriate dress is recommended as this is an active place of religious worship.

The patron saint was chosen through a drawing among various religious devotions, resulting in the selection of Saint Jude Thaddeus. This unusual selection method reflects the community's spiritual traditions and local decision-making practices.
