Atrodas Gatartas centrā uz reljefa virsmas paaugstinājuma. Muižas pili cēla laikā no 1823. - 1824. g. (fasāde - klasicisma stilā). Tās ieeju vēl pavisam nesen rotāja divi (postīti) lauvu tēli. Par muižas kompleksa varenību liecina vēl 20 citas ēkas (dažādā stāvoklī, g.k. – sliktā!) – ļoti iespaidīgs ledus pagrabs, dārznieka un kalēja māja, klēts, magazīna, alus brūzis, Kundziņkrogs, kas atrodas plašākā teritorijā. Daļēji saglabājies 19. gs. veidotais parks. Drustu muižas īpašnieks – vācbaltietis un pētnieks Ludvigs Kārlis Augusts fon Hāgemeisters (1780. – 1833) 1806. g. organizēja un vadīja Krievijas ekspedīciju uz Aļasku. Šobrīd muižas pils ir privātīpašums un apskatāma no ārpuses.

The castle was commissioned by Baron Alexander von Fittinghof and built between 1859 and 1863 in the late Tudor Neo-Gothic style.  It is one of the most important monuments to this style in Latvia and has an ornate limestone façade.  The 7th Sigulda Infantry Brigade was housed in the castle from 1921 until 1940.  Today it is home to the Alūksne Museum with a permanent exhibition and an “environmental labyrinth.”  One of the most unusual exhibits is a set of fluorescent minerals that can be viewed under lights with various spectrums.

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.

There are several buildings from the estate that survive to the present day and were built by the Plater dynasty of noblemen.  The old mansion that is on the side of the Count Plater Street was built in 1759 on the banks of the Jāņupīte River.  The Baroque building was designed by an architect from Venice, Antonio Parazzo.  Later the mansion was rebuilt, and after a new castle was erected, the Plater family spent its summers on the first floor of the old building.  The second and third floors had a library with some 20,000 books.  The noblemen managed to move most of the contents of the library to safer locations during World War I, when the library as such was destroyed.  Work on the new castle of the Krāslava Estate (on the upper part of the Daugava River Valley) began in 1756 (architect Domenico Parazzo).  Initially it was in the Baroque style, but reconstruction at the turn of the 18th century involved Classicism.  Unique Rococo wall paintings with views of Rome have been discovered in the building.  These were based on samples from castles in Poland and were painted during the 1760s and 1770.  A high school used the new castle until the 1970s.  Then the building was abandoned and gradually turned into a ruin.  More recently there has been major renovation of the castle’s façade, and it now has a good appearance.  Surrounding the structure is a romantic landscape park that dates back to the mid-18th century.  It is on the hillocks of the Daugava River Valley and the valleys that cross it.  An artificial grotto has been restored, and a statue of a lion stands guard over the site.  The stairway has been placed in its historical location, and the park features pathways and a yard.

Lodes muižas ēkas izvietojušās t.s. Lodes – Taurenes subglaciālās iegultnes (cauri tek Gauja) austrumu nogāzē. Muižas apbūve tapusi 19. gs. pirmajā pusē, bet kungu māju (klasicisma stils) cēla 1815. g. Pēdējie īpašnieki, kas šeit saimniekoja (līdz 1939. g.) – bija Šmidtu dzimta. Mūsdienās muižas pilī vasarās dzīvo LU Ģeogrāfijas un Zemes zinātņu fakultātes studenti, kuriem šeit ir lauku prakšu norises vieta. Kungu māja apskatāma no ārpuses.

On the left bank of the ancient Gauja River valley, between the Paparžu ravine and the ravine along which the Sigulda-Turaida road passes through the valley there are the ruins of a castle built by the Order of the Brethren of the Sword.  Construction on the castle began in 1207, and three decades later, in 1236, the castle was rebuilt for the needs of the Livonian Order.  The Sigulda Castle suffered much damage during wars in the late 16th and early 17th century.  During the Great Northern War, it was burned down and never restored.  What is there today is the south-western segment of the castle's convent building, as well as the tower of the main gate.  Beyond that is the internal forecastle, where there is an open-air stage for the annual Sigulda Opera Music Festival and other public events.  There are also impressive views of the ancient Gauja River valley, Krimulda and Turaida.  Reconstruction of the ruins is currently ongoing, and after the work is completed a second tower on the left side of the stage will be available to visitors.  The plan is to install crossings around the walls of the convent building.  Presently the ruins are available on a 24/7 basis and free of charge, but after the restorations are completed in 2012, admission will be charged.

Druvienas muižas pirmsākumi ir meklējami 17. gs. beigās. Tagad redzamā apbūve ir veidojusies 19. – 20. gs. Līdz mūsdienām ir saglabājusies muižas pils (1898. g.) un saimniecības ēkas – klētis, kūtis, kalpu mājas. Muižas pilī 20. gs. 50. gados izvietoja pamatskolu. Diemžēl sākotnējie ēkas interjeri nav saglabājušies. Pili ieskauj parks. Šobrīd ēkā atrodas Druvienas Latviskās dzīvesziņas centrs, kas piedāvā dažādas aktivitātes un radošās darbnīcas. 

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.

The residential building of the manor house was built in the 19th century. In 1932, so neglected manor house was bought by the Latvian press king A. Benjamiņš. Nowadays, the manor house is owned by the Benjamiņi family again and there is located a photo exposition of the private life and travels of A. Benjamiņš.

Found along Liepājas Street, which is the old road from Livonia to Prussia, the ruins are a symbol of Aizpute and are depicted on its herald and its flag.  Work on the castle began around 1248 and was done during the role of Dietrich von Grenningen, master of the Livonian Order.  It was a castella-type stone castle with a tower at one corner and wooden buildings in the courtyard.  The bishopric of Kurzeme was in Aizpute during the Middle Ages.  The castle was abandoned after the Livonian War in the latter half of the 16^th century, but it was restored in the early 17^th century, with annexes being added to it.  Part of the castle had residential flats until the 1970s.  The ruins have been preserved to a certain extent, but it is dangerous to clamber upon them, so that is forbidden.  Aizpute is one of the oldest towns in Latvia, with written information about it dating back to 1378.  100 m to the East of the ruins is a stone bridge, which is one of the newest bridges in Latvia.  The stone railings were presented by Baron Karl von Manteufel, and the bridge was installed in 1907.  The granite plaque on the railing on the north end of the bridge has the herald of the Manteufel dynasty, though it is hard to see.
