The parish church in Wińsko was first mentioned in sources in 1272 (parish priest Nicholas) and again in 1354 under the call of the Blessed Virgin Mary. In 1432, it was destroyed by the Hussites, but it was rebuilt ten years later. During the town’s fire in 1514, the church again was almost completely burned down, only the peripheral walls remained. The rebuilding was carried out in the years 1549-1562. From that moment the church was already carrying the call of Holy Trinity, as it was taken over by Protestants. Due to lack of funds, the planned tower was not constructed, only a wooden belfry was erected. In the years 1669-1671, the building was thoroughly renovated. In 1696, in realtion with the Counter-Reformation in Silesia, after the death of the last pastor, the church was closed. In the hands of the Protestant commune, it returned only in 1707. In 1826 the sacristy was rebuilt, and in 1876 a neo-gothic tower was added to the west façade. At that time, the walls and equipment of the building were also renovated.
The church is a building orientated on the east-west line, made of brick. In the 16th century, it consisted of a three-bay and three-aisle nave in a hall form. On the eastern side, a narrower, elongated, three-side ended chancel was added. The block of the church was surrounded by buttresses, and the eastern gable of the naves was decorated with blendes. Along the upper external facades of the naves and chancel, a toothed frieze was guided. Between the buttresses there are large, pointed windows with tracery in the upper storey and smaller windows closed by a semicircular arch in the lower storey. The interiors were covered only with timber ceilings.
