The Zasa Lutheran Church is in the northern part of the Zasa park, was built in 1750, and is a small Lutheran church. The organ, which was produced by the distinguished organ builder Andrejs Sūnākslis, was recently restored. The graves of German soldiers who fell during World War I are near the church.

Located on the right bank of the Daugava, the church can be seen from various parts of Piedruja.  The first wooden church was built at the instruction of Prince Jan Stapekha in 1632, and it burned down in 1759.  The Baroque stone church that is there now was built in 1759 with its two towers, and it may have been designed by an Italian architect.  The towers stand 27 m high, and under the church is a cellar.  The towers have three bells – the largest one dates back to 1711, the middle-sized one was manufactured in 1896, and the smallest dates back to 1619.  The largest bell weighs nearly 0.4 tonnes.  Inside the church are many important cultural and historical monuments, including a central wooden altar with a painting of the assumption of Mary, three 18th century altars, a pulpit from the early 19th century, St Anton’s altar, a fresco of the Holy Trinity, church dishes from the 17th century, etc.  The building is surrounded by a large garden with a stone fence and stone repositories at the corners of the garden.  Two priests, Kazimirs Konvalevskis and Broņeslavs Stefanovičs are buried here.  Stefanovičs played a major role in the restoration of the church after World War I.  The Piedruja congregation first emerged during the first half of the 17th century.

Construction of the church began in 1830 thanks to money donated by nobleman Ludvigs Šabanskis.  The Baroque stone church is surrounded by a restored stone fence, and inside there are icons including "Heart of Jesus," "Christ's Suffering," and "St Joseph."  The church is not open to the public on a daily basis.

Kolka Evangelical Lutheran Church. A story has survived of one Danish trader saved in a shipwreck at Kolkasrags who in gratitude built a church in Kolka. The church had changed its location for three times in Kolka. The foundation of the church visible nowadays and built of boulders was laid by Karl Ludwig Ferdinand von der Osten-Zaken, the former owner of the Dundaga estate. It was built instead of the wooden church (or close to it) which was heavily damaged during the Crimean War. The first construction works were started in 1885 by the construction foreman Otto Sievert (Architect: T. Zeiler). In the Soviet time, the church was vandalized and it was used as a warehouse. It is worth to see the modern- style altarpiece
(a donation of the artist Helen Heinrihson) which does not have a counterpart in any other church. Before in its place there was placed a cross.
Kolka Orthodox Church. Data on the Liv turning to orthodoxy are provided by a document found in the tower of the Kolka Orthodox Church (see also below) during restoration works (the nineties of the last century) that was placed there during building of the church in 1885. It says that the Liv turning to orthodoxy or the so-called emperor's faith "has nothing to do with the religious belief but it is a means to get the earthly benefits or pleasures." In 1885, the orthodox congregation purchased land from baron Osten-Zaken. In 1890, a church, priest's house and school building were built on it. All the buildings have survived until now. The church has its own congregation and worships are held once a month. Information is found that Kolka is the only Liv coastal village where in the nineties of the 19th century there was built an orthodox church. The church bell is place "occupied" in 1936. In the Soviet time, the Church was used as a chapel but nowadays it performs its original role.

On sunny days, this white church absolutely sparkles. It is in the southern section of the village and can be seen from a great distance. Jesuits built the first wooden church at this location in 1759 in honour of St Peter and St Paul. The church that is there today was built nearly a century-and-a-half later, in 1893. The interior can be visited during worship services. Interred in the yard of the church is the Lithuanian pastor and wood carver Antons Rimovičs (1865-1933). The congregation building is opposite the church.

Atrodas Iecavas upes ielokā starp Rīgas un Sporta ielu. Baznīcas celtniecību uzsāka 1641. g. un pabeidza ap 1657. g. Ēka ievērojami cieta 2. Pasaules kara laikā. Pie baznīcas atrodas kapi, kuros apglabāti grāfu Pālenu dzimtas pārstāvji. To ziemeļaustrumu stūrī redzama Pālenu dzimtas kapliča. Baznīca ir it kā „sadalīta” divās daļās – vienā daļā notiek restaurācijas darbi, otrā izvietota bibliotēka. To ir vērts redzēt arī no iekšpuses.
