The estate owned by the dynasty of Baron Osten-Zaken was rebuilt in 1856 and 1857, because the old estate was sacked during the Crimean War (1853-1856).  At the beginning of the war, British warships bombarded Latvia's shoreline and ships with the purpose of scaring the Russian tsar.  Some of the gunfire hit Kolka, which was part of the Russian Empire at that time.  After the estate was destroyed, the so-called White House was built there with a series of ancillary buildings.  A mantel chimney was installed on the second floor, and it was used to smoke wild game (the chimney is still there).  The estate belonged to the aristocrats until 1919, when its last owner, Christian von Osten-Zaken, was shot in Tukums.  An elementary school, known as the Kolka School, was installed in the White House in 1929.  It remained open until 1961, when a new school was built.  Crafts lessons were offered at the building until 1989, at which time it was known as the Old School or the Small School.  In 1991, the Old School was taken over by the Faculty of Biology of the University of Latvia, and it has been used for summer internships for students ever since 1994.

С XV века в Приекуле правил род баронов Корфов. Один из них – Иоганн Альберт Корф (1697 - 1766.) был президентом Петербургской Академии наук (1734 - 1740 гг.), дипломатом и литератором, который занимался исследованием истории Курземе. Приекульский замок находится на западе от улицы Айзпуте, на берегу реки Вирга. Первоначально дворец господской усадьбы построили в XVIII веке, а в конце XIX века велись большие работы по перестройке здания (проект Пауля Макса Берчи). В здании находится Приекульская средняя школа. Примерно в 100 м к востоку от господской усадьбы возвышается смотровая башня усадьбы (построена в конце XIX века), над которой развевается государственный флаг Латвии.

The Jelgava Castle stands between the Lielupe and Driksa rivers. The Baroque castle was designed by the well known Italian architect Francesco Bartolomeo Rastrelli, and this was the most important piece of early work that he did. The Latvian Agriculture University is housed in the castle today. A museum was established in 1968. +371-6300-5617. The socle story of the south-eastern wing has the graves of rulers from the Duchy of Courland – members of the Kettler and Byron dynasties, which ruled from 1569 to 1791. There are 18 restored sarcophagi here.

One of the largest castles in Kurzeme, this building has been preserved in fairly good shape.  Work on its began in the mid-13th century, and it was commissioned by the heads of the Dome Cathedral in Rīga.  In 1434, the estate was bought by the bishop of Kurzeme.  The Maidel and Osten-Sacken dynasties owned it from the 16th to the 20th century.  The Dundaga Castle burned down twice and has been rebuilt many times.  The last reconstruction was in 1905, after the castle was burned down during the revolution.  Of interest on both sides of the castle’s door are stone carvings of a knight and a bishop.  In recent years, the hotel in the castle has been renovated, as has the second floor hallway and a terrace that is popular for weddings.  There are many legends about the castle, including one about a wedding of elves and another about the Green Lady.  Today the building houses the Dundaga School of Music and Art, a hotel, party rooms, the Dundaga Tourism Information Centre and various exhibitions.  It is worth finding a guide to tour the castle.  Groups of tourists can also order tastings of local foods.

One of the oldest buildings at the Pope Estate is the old hunting castle that was built in 1653. The mansion was built in 1608 or 1620. The Neo-Gothic porch was added in 1840. The interiors of the mansion have been preserved since the 18th century and the 3rd quarter of the 19th century, including wood panelling, original decorated ceilings, a front door in the style of Classicism, and a Rococo stove.  Sadly, one of the oldest buildings - the home of the estate's governor - burned down in 2018, but the rest of the estate did not suffer and retained its beauty.  Visitors will be delighted about the aromatic garden of phloxes, as well as the impressive oak trees. Worth a look is the hillock behind the main building of the estate, near which there used to be a narrow-gauge railroad (the Pope Station).  The other buildings cover a fairly extensive territory, and so it is worth spending a few hours to tour the village of Pope.

The Pope Estate and its park are among the best-preserved estates in the area.  Since March 1941, it has housed a school.  Most of the trees in the park are common, but there are a few rare ones.

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.

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 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 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.

Skaistā ēka atrodas Lizuma centrā. Lizuma muižas īpašumi piederējuši dažādām dzimtām – vācbaltiešiem Tīzenhauzeniem, Malamiem un Volfiem. 1836. g. muižu iegādājas barons Otto Gotlībs fon Volfs, kura laikā muižas pils iegūst tagadējo veidolu – Tjudoru neogotikas stilu ar poligonālu torni. Jau no 1937. g. pilī izvietojusies Lizuma skola, kas ir viens no iemesliem, kādēļ saglabājusies ne tikai pati ēka, bet arī atsevišķi interjera elementi kāpņu telpā, Zilajā (Mednieku) zālē u.c. Pili ieskauj parks, kur atrodas muižas saimniecības ēkas – mūra klēts (te kultūras nams), 1876. g. celtais zirgu stallis (sporta halle), kalpu un dārznieka namiņš u.c. Bijušajā spirta brūzī ražo Gotiņas konfektes. Pils tornī izveidots Lizuma vidusskolas veidotais novadpētniecības muzejs.
