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 Baisogalo Estate is one of the oldest ones in Lithuania and is known as a royal castle because it once belonged to the local lord.  The ornate late-Classicism buildings were built in the mid-19th century and have survived.  The 12 ha landscape park dates back to the early part of the 19th century, with an alley of chestnut trees leading to the estate from the local village.  The central alley that starts at the gate weaves through two curvy bodies of water with a bridge and statues of lions.  Various trees behind the estate are alongside curvy and narrow pathways.  On both sides of the alleys are bodies of water, and deep in the park is a pond with an island.

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.

Olustvere is one of the best preserved manor estates in Estonia. The building complex is set in landscaped grounds in English style with avenues of old trees. Collections of stuffed birds, hand-carved wooden horses with tools and antique furniture are exhibited in the complex. Other buildings and facilities include a distillery, a smithy and handicraft, wool, clay, ceramics and glass workshops where visitors can try their hand in various crafts. The mansion now houses a tourism centre.

The Livonian Order built a fortified castle on the largest island in Lake Alūksne – Marijas Island (Pilssala Island) in 1342.  It was linked to the land by a 120 m drawbridge.  The castle had several forecastles, and it was regularly modernised and expanded until the end of the 17th century.  It was one of the largest Livonian Order Castles, with similar ones found in Vastelina and Izborsk.  Defensive barriers were put up around the castle, which survived until the Great Northern War.  Its central part was blown up by the defeated Swedish military in 1702, after which Russians completely sacked it.  All that is left are the castle ruins on the island, which is now linked to Alūksne and Temple Hill by two wooden bridges.  An open-air stage alongside the castle ruins is used for various public events.

The estate is in the centre of Ineši, 5 km to the south of Vecpiebalga.  The estate dates back to the latter half of the 17th century, when an ornate castle for the noble Sheremetyev family was built here in the style of Classicism and on the banks of the little Orisāre River.  The castle was built down during the 1905  Revolution, but restored four years later.  Around the castle is a lovely landscape park.  The castle served as the prototype for the Slātava Estate in the famous novel “Age of the Surveyors” by the Kaudzīte brothers.  In 1992, the Piebalga Administrative District Museum was opened in the wine cellar of the castle, which is home to the Ineši Parish Council and a porcelain painting studio.  Organised tours of the estate and its surrounding area are available.

Muižas ēka tikusi restaurēta, taču tā celta 1732. gadā. Muižas kompleksu veido – kungu māja, bijušās skolas ēka, pārvaldnieka māja, klēts, saimniecības ēka, kā arī tējas namiņš, kas atrodas senajā ozolu parkā, no kura takas tālāk aizvijas uz Meža parku. Ungurmuižas  iekštelpās ir grezni zīmējumi (grenadieri, ziedu motīvi, zīmētas tapetes, drapēri, ainas no barona karagājieniem un ceļojumiem) kuru autors ir Limbažu gleznotājs Georgs Dītrihs Hinšs. Ungurmuižā par seno auru rūpējas katrs gleznojums, zīmējums un katrs nostūris.

The first stone castle in Alsunga was built in 1372, starting with the central part of the southern wing. The authorised representative of the Livonian Order, who was subject to a higher-ranking official in Kuldīga, lived here. The guard towers and other parts of the castle were gradually added between the 15^th and the 18^th century. The Baroque castle with its two towers is quite impressive. The castle is unique in and outside of Latvia in that it is one of the rare Medieval castles to have survived to the present day in part, but in its original historical appearance.  The castle offers an exhibition about its history.  Visitors can look at a Suiti kitchen, write a letter with a fountain pen in Barbara’s boudoir, or celebrate a special event in the romantic venue of the castle’s round tower. Renovation of the castle began in 2018, and it is closed to visitors.  Still, you can look at its exterior and tour its garden.  

Виргская господская усадьба как лен была передана вассалу Ливонского ордена Конраду Нолду. До наших дней сохранился дворец господской усадьбы «Виргас», в котором с 1935 года до наших дней разместилась школа. Во дворце находятся три двери, украшенные красивой резьбой по дереву, с гербами рода Нолдов и портреты баронов. В бывшей клети господской усадьбы в 1983 г. обустроен Дом традиций - теперь Дом культуры. Господскую усадьбу окружает парк, в котором находится место могилы барона Нолда и баронессы с памятником. В центре Вирги установлен сапог Карла XII с двумя направленными друг от друга пушками и ядрами, которые вещают о временах Северной войны, когда в Вирге в 1701 г. был лагерь шведского войска.
