The parish church of St. Bartholomew was built around 1484. At that time, the village was owned by Zaklika Małogórski. In subsequent centuries it was expanded, in the seventeenth century, a sacristy was added, and in the eighteenth century, a tower was added. A thorough renovation of the church was carried out, among others in 1924 and 1932. During this time the portal was removed with the date of church construction. After the Second World War, the church was renovated in 1966. At that time, a new interior polychrome was made.
It is a single-nave, timber church of a log structure and timbered walls. It is composed of a three side ended chancel and a wider nave built on a rectangular plan. From the west, a tower was added, erected in a pole structure with sloping walls and an overhanging porch. The interior is supported by six pillars and covered with flat ceilings.
The log structure in the church in Łęki (similarly to other 15th-century churches from the Małopolska region) was shaped in a characteristic way, slightly narrowing towards the top of individual frames, which resulted in visible external sloping, especially in the upper parts of the framework face towards the interior of the building. The method of connecting frames in the corners was varied, but regardless of how the logs were joined at the corners, the connections were always accompanied by so-called covered pin, i.e. the element stiffening the bond itself. This was the basic factor distinguishing the early medieval, primitive construction from that used by professional carpenters from the period of late Gothic.
The chancel and the wider nave have retained their original Gothic character to this day, but to the west there is an 18th-century Baroque tower and a modern sacristy to the north. Two Gothic ogival portals from the end of the 15th century have been preserved in the church.
