Pirmie dokumenti par Kokmuižu atrodami 1601. gada zemes revīzijas pierakstos. Tur sniegtā informācija vēsta, ka Kokmuiža pastāvējusi jau 1560. gadā. Taču 1880. gadā vācu muižnieks sākas celt kungu māju neobaroka stilā. 20. gs. sākumā tā tika izpostīta, bet 1937. gadā to pārveidoja par skolu.

Kokmuižā kādreiz atradusies alus darītava. Tas bija laika periodā no 17.- 20. gs. Tā bija viena no slavenākajām alusdarītavām visā Vidzemes guberņā.

Mūsdienās var izstaigāt muižu pats vai gida pavadībā. Var aplūkot kungu māju, staļļu ēkas, muižas pārvaldnieka namu, bibliotēku, ekspozīciju, abas klētis un alus darītavas pagrabu, kā arī sfērisko saules pulksteni.

Several of the buildings of the Šlītere Semi-Estate have survived to the present day – the servants' house (late 19th century), the pump house (mid-19th century), the smokehouse (mid-19th century), the cattle barn, etc.  A forestry building was built here in 1936 and renovated in 2010.  Since the end of 2009, the administration of the Slītere National Park has been housed here.  Today the building also houses the Kurzeme regional branch of the Environmental Protection Board.  Opposite the building are two yews, and there is a productive ivy which has covered the northern side of the servants' house.  The common yew and the Baltic ivy are symbols of Šlītere, and you can see and photograph them here without "bothering" them in their natural environment.  The pump house contains a well that is unique in Latvia – it is 34 m deep, which is nearly the height of the Blue Hills of Šlītere.  It reportedly was active until the 1970s and delivered water to the forestry system.  A fragment of the stone well can be seen as a part of the wall of the pump house.  The semi-estate is surrounded by small elements of a park, including an impressive alley of elm trees.  Locals says that pre-war Latvian President Kārlis Ulmanis spent the night at the building once while on a hunt.

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.

Līdzmūsdienām ir saglabājusies vecā - 18. gs. vidū klasicisma stilā celtā vecā kungu māja (šobrīd netiek izmantota, skaisti sīkrūšu logi!) un tai iepretim - pēc 1905. g. ugunsgrēka atjaunotā (1912. – 1913. g., neoklasicisma stils) jaunā pils, kurā atrodas Īvandes pagasta pārvalde, bibliotēka un jauniešu tūristu mītne. Ēkā saglabājušies atsevišķi interjera elementi – parketa grīdas, koka kāpnes u.c. Muižas parkā joprojām zaļo Baltijā lielākā Eiropas baltegle. Tās augstums pārsniedz 32 m, apkārtmērs - 4 m. Parkā izveidota atpūtas vieta.

Tāšu – Padures muiža (Tasch – Paddern) celta 19. gs. sākumā kā Korfu dzimtas pils, kas 1852. gadā pāriet Keizerlingu dzimtas īpašumā kā medību pils, kas kalpojusi kā vasaras mītne, un ir izcils vēlīnā klasicisma paraugs. Iekštelpās saglabājušies vairāki senā interjera apdares fragmenti. Pēc pils pabeigšanas, ap to sāka veidot vairāk kā 10 ha lielu parku ar svešzemju kokiem. Šobrīd muižas ēkā atrodas Kalvenes pamatskola.

Muižas dzīvojamā ēka līdz mūsdienām nav saglabājusies. Šodien Dvietes muižas parkā ir apskatāmas muižas pārvaldnieka māja un trīs mūra saimniecības ēkas. 19. gs. veidots ainavu parks ar laukakmeņu mūrējuma tiltu. Parkā atrodas Dvietes muižas ēkas.

The historical centre of the Tāšu Estate is in the Ālande (Telse) River Valley near Lake Tāši.  The current estate was built by the von Korff dynasty, and the mansion dates back to 1734.  Inside there are valuable Baroque fireplaces, the main entrance portal made of sandstone from Gotland, the original stone floor in the hall, parquet and wall panels.  The front door, windows, stairs and other details were installed in the early 19th century

The Šilute Estate is often described on the basis of its last owner, Hugo Scheu, who bought the estate in 1889.  He restored the estate's buildings and territory, also installing two parks, one for the estate, and the other one known as the "raven forest." Alongside the estate is an English-type park with strolling trails.  The park is used by local residents and is on both sides of the curvy Scheu River, with the banks connected by pedestrian bridges.  He park stretches to an old railroad bridge and has approximately 150 types of plants, including 40 types of trees and shrubs.

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.

The castle was built during the first half of the 19th century in Tudor Neo-Gothic forms.  The first owner of the castle was Baron Johann Gottlieb von Wolff.  During the 1870s and 1880s it was rebuilt in the style of French Neo-Renaissance.  The castle was burned down during the 1905 Revolution, but it was restored with certain elements of Art Nouveau forms.  Tours are available of the interior of the building.
