The oldest elements of the Oleri Estate date back to the 17th century.  Initially there was a wooden mansion with an ancillary building.  The new centre was built in the late 18th century in the style of Early Classicism.  After agrarian reforms, the mansion housed an elementary school, and during the Soviet occupation and until the 1970s it was a school for children with mental disorders.  The mansion suffered in a fire in 2000, after which it was restored.  A local organisation was of great importance in this regard.  The mansion is known for its Classicist paintings, with a unique “Painting Gallery.”  The mansion is surrounded by a lovely park.  The Oleri Estate is known for hosting chamber music concerts.  The local Oleri swamp has a wooden pathway and a little viewing tower.

Muiža vēsturiskajos avotos ir minēta jau 1560. gadā. Tagad redzamā kungu māja ir celta no akmens 1805. g. Padomju laikos tajā atradās Matsalu rezervāta administrācija, bet mūsdienās ēkā ir izveidota viesnīca. Līdz muižai nokļūstam pa skaistu aleju, kuras apkaimē ir redzamas citas muižas kompleksa ēkas.

Muiža sāka veidoties 16. gs. beigās (īpašnieki - Tīzenhauzeni, vēlāk Bēri), bet no 1753. g. tā kļūst par Mēdemu dzimtas īpašumu. Tagad redzamo muižas pili (mūsdienās tikai atliekas) cēla 1806. - 1810. g. klasicisma stilā (Johana Georga Ādama Berlica projekts) pēc itāļu izcelsmes Pēterburgas galma arhitekta Džakomo Kvarengi meta. Muižas īpašnieks tajā laikā bija Johana Frīdriha Mēdema dēls - Kristofs Johans Frīdrihs (saukts par Žanno). Elejas pilī bija savākti daudzi nozīmīgi Eiropas mākslinieku darbi, kā arī iekārtots izcils interjers. 18 muižas kompleksa ēkas nodedzināja Pirmā pasaules kara laikā (1915. g.) un līdz mūsdienām ir saglabājušies tikai nelieli pils pirmā stāva drupu fragmenti ar kaltiem portika kolonu kapiteļiem, pārvaldnieka māja (apskatāma no ārpuses), atsevišķas saimniecības ēkas un parks. No pils drupām pa aleju var aiziet līdz Tējas namiņam (bēdīgā stāvoklī). 0,5 km ziemeļos no pils drupām atrodas 1912. g. izveidotā Mēdemu dzimtas kapsēta. Elejas pils mūra žoga arkādē iemūrēts dobumakmens.

The palace was built as the summer residence of the duke of Courland, Ernst Johan Byron, and it was designed by the outstanding Italian architect Francesco Bartolomeo Rastrelli. The construction of the palace ensemble took place between 1736 and 1740. The decorative finishing of the interiors was carried out from 1765 to 1768 by the sculptor Johann Michael Graff and the painters Francesco Martini and Carlo Zucchi. The significance of the palace lies in its authenticity as it has not been modified through rebuilding since then. Intensive restoration works started in 1972 when the Rundāle Palace museum was established. The restoration was completed in 2018.

All that remains today is the governor’s house in which the Latvian author Rūdolfs Blaumanis (1863-1908) lived from 1885 until 1887, and a stable built of fieldstones.  The Central Daugava Forestry Centre of the Latvian State Forests company is located in the building.  The stone gates of the Koknese High School where once the gates of the estate.  The buildings can mostly be viewed from the outside.

The Lielstraupe Castle is the only building in Latvia which contains a Medieval castle and a church.  Work on the castle began in 1263.  The building suffered great damage during the 17th and 18th centuries, as well as during the riots of 1905.  The complex was restored in 1909 by the architect Wilhelm Bockslaff.  There are several artistic monuments in the church – the organ loft from the 17th century and the pulpit paintings of the 18th century.  In 1944, two stained glass windows produced by the artist Sigismunds Vidbergs were installed at the church – Golgotha and Birth of Christ.  The tower contains a clock produced by a local clockmaker, and there is a sun dial on the wall of the church.  Visitors to the park of the castle will see the wooden bell tower which dates back to 1744.  A memorial plaque to men who fell during World War I and Latvia's liberation battles was installed in the church in 1938.  A drugs treatment hospital was installed in the castle in 1963.  The church is open during worship services, and the rest of the complex can only be viewed from the outside.

The Ance Estate was built for Ulrich Johann von Behr by his father as a gift.  The estate was once surrounded by an ornate French garden.  Beginning in 1766, the building was rebuilt and ornately decorated.  Around 1810, French soldiers occupied the mansion and caused much damage to it.  For that reason, the second floor was torn down a bit later, and extensive renovations were conducted to adapt the estate into apartments for the manager and his civil servants.  In 1920, the estate was taken over by the state.  

The lady of the house will teach visitors to bake carrot buns and talk about the history of the pastry. The workshop of a craftsmanship group offers a look at the work of craftsmen and a chance to try the crafts yourself.

This beautiful castle (1797-1802) is seen as the most brilliant example of Classicism in Latvian architecture.  It, like the Eleja Castle, was designed by the architect of the royal court in Russia, Giacomo Antonio Domenico Quarenghi and the architect Johann Georg Adam Berlitz.  The ornate interior was unique for Kurzeme at the time when the castle was built.  Empress Catherine II gifted the castle to Charlotte von Lieven (1742-1828) after Charlotte served as governess for the empress’ grandchildren.  An agricultural school operated in the building from 1921 until 1941, and it was very much damaged and pillaged during World War II.  Restoration began later, when the Mežotne experimental selection station was housed in it.  The lovely building houses a hotel and can be toured.  Around the castle, which is on the banks of the Lielupe River, there is one of the most beautiful English-type gardens in Latvia – perfect for a stroll.
