The New Sigulda Castle was built between 1878 and 1881 for Prince Kropotkin.  Its tower was extended in 1937.  From 1923 until 1940, the building was known as the Writers Castle, and it was managed by the Latvian Press Association.  During the Soviet era, a cardiology sanatorium was housed there.  In 1993, the Sigulda City Council took over the castle, and since 2003 it has been home to the Sigulda Administrative District Council.  The wooden residential building (mid-19th century) in which the Kropotkin family lived still survives, as do the granary (late 18th or early 19th century), the gardener's house (19th century), and the stone wall (19th century).  The New Sigulda Castle is part of the historical centre of the Sigulda, Turaida and Krimulda complex, as are the ruins of the Sigulda Castle and the Krimulda Castle, the Krimulda Estate and the Turaida Castle.

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 rakstos pirmoreiz minēta 17. gs. sākumā, taču klasicisma stilā celtās pils veidols tapis 1835. gadā. Penijē muižas būtisks likteņa pavērsiens (atšķirībā no daudzām citām muižām) bija apstāklis, ka tajā izveidoja Matsalu rezervāta (pirms nacionālā parka izveides) apmeklētāju centru. 2000. gadā muižas pili restaurēja un tajā ierīkoja nelielu ekspozīciju. Apmeklētāju centrs te pastāv joprojām, tādēļ šeit var iegūt nepieciešamo informāciju. No ārpuses var apskatīt arī citas muižas saimniecības ēkas.

Found on the right bank of the Daugava where the little Karikste river flows into the Daugava, all that remains of the castle today is a set of ruined walls and foundations.  The castle was built by the Livonian Order in 1224, and it was inhabited until the mid-17^th century, when it was sacked during the Polish-Swedish war.  The ruins offer a good view of the local gravel road that goes along the right bank of the river valley.

On the right bank of the Bērze River and in the western part of Dobele, the castle hill and its fortified forecastle were occupied between the 10th and 13th centuries, with an ancient town at its foot (currently the square between Tērvetes Street and the Liepāja highway).  As was common, the Livonian Order used this ancient Semigallian castle hill to build a brick castle between 1335 and 1347.  The castle was sacked during the 18th century, and its fairly impressive and beautiful ruins have been conserved.  A viewing platform is part of the charm.

The Preiļi Estate is in the southern part of Preiļi. During the Soviet era, the mansion was home to a variety of institutions. A fire burned much of the upper part of the building in 1978. The mansion was never restored, and it can only be viewed from the outside. Around it, however, is one of Latvia’s most outstanding landscape parks (mid-19^th century). Irēna Kjarkuža offers interesting tours of the state, with interesting legends and songs in the Lettigalian language.

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 Trakai Island Castle is the only East Europe's castle which is built on a little island. The process of building this castle started in 14th century. After its fall on 1410 during a war it lost its meaning as a military base and became a living place for ruler of Lithuania. Trakai Castle is one of the most popular objects in Lithuania for tourists. Inside the castle is a museum which tells about Trakai history. 

The manor’s castle was built in the middle of the 18th century (belonging to the noble kin of baron Medem) as a huntsmen castle. Later, in the 19th century, it was rebuilt by adding a second floor. The kitchen was situated in the vaulted basements of the castle and when the food was ready, it was brought upstairs in the elevator. The gantry entrance of the castle (late baroque) and marble buttons above it picturing the coat of amrs of the union of Medem and Keizerling noble kins, is one of the most valuable example of arts monuments of the 18th century. To this day there are various  outhouses preserved- a  threshing barn, a granary and a smithy, as well as the park. In front of the castle one can see a magnificent oak, which was supposedly planted by K.Ulmanis. From 1837 the manor’s castle has also served as a place for Vilce primary school. 

Находится ~ в 1 км на восток от центра Априки. Дворец господской усадьбы (стиль барокко) строился с 1742 по 1745 гг., а башня неоготического стиля как пристройка возводилась в конце XIX века. На фронтоне главного фасада дворца выполнен рельеф из песчаника с гербом родов баронов Остен – Сакенов и Корфов, который является самым роскошным элементом среди подобного рода имений Латвии. В здании сохранились и первоначальные элементы интерьера (осматриваются в сопровождении гида) – дверные створки, расписанная голландская печь, оконные дубовые ставни, коробки, чеканные металлические детали и паркет. В комплекс господской усадьбы входит дом управляющего, дом прислуги, хозяйственные постройки и парк. С 1920 года во дворце господской усадьбы действует школа и устроен музей края, который непременно следует посетить! Сейчас в музее выставлена коллекция этикеток производимого в Латвии хлеба. В 1901 году господскую усадьбу приобрел Карл Густав Маннергейм (1867 - 1951), который был президентом государства Финляндии и легендарным автором системы фортификации линий Маннергейма - Зимняя война (1939 - 1940).
