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.

Muiža vēsturiskajos dokumentos pirmoreiz ir pieminēta 16. gs. Tagad redzamā vienstāva kungu māja ir vairākreiz pārbūvēta laikā no 17. – 19. gs. 1997. g. ēku vēlreiz atjaunoja un tagad tajā atrodas viesu nams un Vilsandi nacionālā parka apmeklētāju centrs, kur var iegūt ne tikai vērtīgu informāciju, bet arī apskatīt Vilsandi apkārtnē atrastās fosilijas. No Lonas muižas var uzsākt pārgājienu uz Vilsandi salu. Vienā no muižas ēkām ir izveidota Vilsandi nacionālajam parkam veltīta ekspozīcija.

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.

Dabiskā zemesragā starp Lielo un Mazo Ludzas ezeru 14. gs. beigās slejās seno latgaļu koka pils, kuras vietā Livonijas ordenis uzcēla Latgales varenāko mūra pili. Tā bija iespaidīga trīsstāvu celtne kvadrāta formā ar sešiem torņiem, trīs vārtiem un divām priekšpilīm. Pēc krievu iebrukuma Latgalē 1481. g., Ludzas pili atjaunoja 1525. g. 1654. g. to atkal izposta Krievijas cara Alekseja Mihailoviča karaspēks. Jau 18. gs. no pils bija palikušas tikai drupas, kas arī mūsdienās ir ļoti iespaidīgas un ainaviskas (ar skatu uz Lielo Ludzas ezeru un baznīcu torņiem).

The construction of the state began in the early 20th century.  The mansion was built of bricks and fieldstones between 1905 and 1911 in the styles of Historicism and Art Nouveau.  The estate was owned by engineer and professor Stanislav Kerbedz from St Petersburg, the first Russian engineer to develop principles for the architectonic aspects of bridges.  These were used during the latter half of the 19th century, and Kerbedz led the construction of the Nikolayev bridge across the Neva River in St Petersburg.  Kerbedz’s wife, Yevgenia, was well known as a lover of art, and she brought various art objects to the estate from Italy.  The Lūznava Estate was a popular place for gatherings of artists during the summers.  Among those to visit was the distinguished Lithuanian painter and composer Mikalojus Čiurlionis.  The estate is surrounded by a 23.7 ha landscape park with a system of ponds.  Near the estate is a statue of the Madonna, which was carved by an unknown Italian artist.  The statue was damaged and thrown into a pond during World War II, but it was restored in 1991.  Reconstruction of the main building of the estate was complete in 2015, and today it is a modern and international centre for environmental education and the arts.

A very impressive ensemble that is in terrible shape.  The estate dates back to the 18^th and 19^th century, with the castle being built in the early 19^th century.  Half a century later it was rebuilt in the Neo-Gothic style with symmetrical towers and bricks in the cornices.  The estate belonged to the Manteufel-Stzege dynasty.  The vestibule, stairwell and second floor hall still have ornamental ceiling paintings, but visitors are not allowed to enter the building, so they cannot be seen.  Valuable interior design elements include a fireplace from the early 19^th century that is decorated with marble elements.  After the expropriation of the castle in 1920 and until 1951, the building housed a forestry school and then an agricultural crafts school.  Opposite the castle was the stable of the state that was built in the style of Classicism with a pediment and mighty columns.  Built in the early 19^th century, the stable is no longer used and can only be viewed from the outside.  A very much overgrown park surrounds the complex, and the hillock is the grave of one of the baron’s dogs.

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 Castle of the Livonian Order in Ventspils was first listed in documents in the late 13^th century, and despite damaging wars, it has maintained its essence as a castle to this very day and only with minimal changes. The castle is also known as the oldest Medieval fortress in Latvia. Today it is home to a modern museum.

The Raudondvaris Castle is on the right bank of the Neveža River in Raundondvaris.  The estate and a park that covers 3.8 ha has two buildings, an orangery, a stable for horses and a cellar.  Alongside the estate in 1834 was a park that was rebuilt in the 20th century with new plants and flowerbeds that featured ancient types of roses.  The northern part of the park is forested, with maple, pine and linden trees, as well as Edelweiss that blooms in the spring.  Paths in the park lead to a local environmentally protected area.

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.
