Traķu pirmsākumi ir meklējami Senajos Traķos, kas atrodas 4 km dienvidaustrumos no Traķu centra. Uzskata, ka Senos Traķus ir dibinājis Lietuvas dižkunigaitis Ģedimins (~ 1275. – 1341.) 14. gs. pirmajā pusē. 14. gs. otrajā pusē šeit uzcēla mūra pili, no kuras līdz mūsdienām ir saglabājušies tikai nostāvināti zemes vaļņi. Laikā no 1345. – 1382. g. tajā valdīja Ģedimina dēls – Ķēstutis (1297. – 1382.). Senajos Traķos dzimis arī viens no izcilākajiem viduslaiku Lietuvas valdniekiem – Ķēstuta dēls - Vītauts Dižais. Kā pilij, tā arī tās valdniekiem bija nozīmīga loma sekojošajos krusta karos un cīņās. 1391. g. pils tika sagrauta cīņas laikā ar Vācu ordeni, kādēļ arī zaudēja savu stratēģisko nozīmi. 1405. g. benediktīniešu mūki šajā vietā uzcēla baznīcu, bet 18. gs. beigās - jaunu un lielāka apjoma klosteri, kura vienu no korpusiem 1889. g. pārbūvēja par baznīcu.

The church was built during the rule of Baron Otto Hermann von Fittinghof and built between 1781 and 1788 by the architect Christoph Haberland.  Built in the style of Classicism, the church has elements of the Baroque style and a set of colourful rocks in a mosaic on the façade.  The organ was built in 1855 by August Martin, and the bell was evacuated to Russia during World War I.  The congregation replaced it with a much older bell (1530).  The altar painting, “Baptism of Christ” was pained by an unknown artist and was restored in 2000.  During the mid-19th century, there were many Estonians in the congregation, so worship services were held in Estonian, too.  The church was restored in 1934, and now it dominates the city with its 55.5 m high tower.

18 A. Upīša Street. The church was built in 1897 in the Neo-Gothic style (Architect H. Shel) and it is one of the few19th century city brick buildings. In the church there is the altarpiece "Christ healing the sick" - I. Zeberliņš (1943). You can see the church from the inside during the worship or by a prior arrangement. Near the church, you can see a monument designed by E. Laube (1926) to 80 Latvian riflemen who died in World War I and who were buried in the Warrior's Cemetery near the river Vēršupīte. Near the cemetery, there are also buried J. Kārkliņš and F. Siliņš, fighters of the Kauguri Battle of May 18, 1919. By a prior arrangement, tourist groups can see the church from the inside.

Šo sakrālo celtni uzskata par vecāko Zemgales baznīcu, kas joprojām pilda savu pamatfunkciju. Tās celtniecību uzsāka 1567. g. un pēc nopostīšanas atjaunoja 1614. g. Pēc poļu - zviedru un Ziemeļu kara to atkārtoti atjaunoja 1815. g. Dievnamu var apskatīt arī no iekšpuses.

The Dviete Catholic Church is in the centre of the small village of Dviete. The white church can be seen from a distance. The first wooden church was built here in 1775 by the owner of the local estate, Count J.K. Wischling. Later the church was dismantled and brought the Zarinki cemetery. The Neo-Baroque Catholic church that is seen today has two towers, and its construction was financed by Count Kazimir Plater-Sieberg. The church was destroyed during World War I, and until it was rebuilt and consecrated, the granary of the Dviete Estate magazine, with its ridged roof, was used as a prayer house. It is on the side of the Dviete-Bebrene road and has recently been restored. In 1940, a stone fence was installed around the church with a tiled roof, and a building for the congregation was built in the 1970s. The church features a particularly ornate sacral Baroque interior, which is seen as the most ornate interior of its type in the former Daugavpils District.

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.

The first wooden Catholic church in Dagda was built in 1705, while the church that is seen today was built in the Baroque style during the latter half of the 18^th century, the work financed by a local nobleman.  Important interior elements include the altar, the pulpit, the organ, a monument to the Hilsen dynasty, etc.  To the North of the church is historical Dagda itself, with typical red brick buildings from the early 20^th century that are known as the former homes of Jewish merchants.

The Krimulda Lutheran church is seen as one of the oldest in Latvia. It was built in the early 13th century, soon after the territory of Kubasele was conquered. Over the subsequent centuries, it has been rebuilt many times. Alongside the church is a meditation maze called "Lily Blossom." When the Liv warrior Kaupo fell in battle near Vīlande in 1217, his remains were supposedly interred at the church. Local residents, true, describe a small hillock that is near the church as the grave of Kaupo. The site is located alongside the little Runtiņupīte (Runtiņš) river, on the right bank of which is a manmade cave that is approximately seven metres deep. It is the Kubesele Cave or the Runtiņala Cave. The Kubesele castle hill is on the left bank of the Runtiņupīte. The Kubesele Nature Trail starts at the church. If you hike down the trail, you'll see all of the aforementioned objects and others. The trail leads to the Gauja River where, on the right bank, is the Great (Runtiņš) Rock. Nearby you'll find anchor blocks installed by rafters on the river.

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.
