Braucot cauri Kaives ciemam, var pievērst uzmanību Kaives muižas „atliekām”. Vietas vēsture ir sena, jo jau 1440. gadā Livonijas ordeņa mestrs piešķīra šeit īpašumu Johanam Kaivenam. Kungu māja gāja bojā 1905. gadā, bet pārvaldnieka ēku nopostīja 2. pasaules kara laikā. 1956. g. nodega kalte, bet pirms trijām desmitgadēm - muižas krogs. Līdz mūsdienām palikusi tikai 1861. gadā celtā magazīna (sarkana ķieģeļu ēka) pakalnā un tai blakus esošais parks, kurā izveidots neliels skulptūru dārzs, estrāde un atpūtas vieta.

The Alantos Estate is in the village of Naujasodžio, and it was built in the style of Neo-Classicism in the 19th century.  The estate is surrounded by a park with many types of trees, as well as a set of ancillary buildings.  The mansion is reminiscent of an Italian villa, and the Neo-Romantic park has alleys of trees and three ponds of various sizes.  The trees were planted so that over the course of time, their trunks would grow together to ensure mighty crowns.  Alongside the park are a few gazebos, an obelisk that stands a few metres high, as well as white marble sculptures of Venus and Jupiter.

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.

Muižas pils (no sarkaniem ķieģeļiem celta) ir meklējama ceļu krustojumā pie Gaujām – 2 km ziemeļaustrumos no Jaunpiebalgas centra, Gaujas labajā krastā. Līdz 1918. g. muižas īpašnieki bija slaveno grāfu Šeremetjevu dzimta. Muižas pili nodedzināja 1905. g. nemieros, bet vēlāk atjaunoja. Muižas pilī bijušas dažādas iestādes: slimnīca, kolhoza „Piebalga” administrācija, mūsdienās – pašvaldība un dažādu sadzīves pakalpojumu sniedzēji.

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 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.

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.

The Volkenberga Castle was built in the 13th century by the Livonian Order, and it was practically impregnable, as it was on top of Mākoņkalns hill.  These were among the first fortifications in Latgale, and only fragments of the castle remain today.  Architect Pēteris Blūms has said that this was a special type of fortification.  Legends say that after the lord and lady of the castle died, the property was divided up among their three daughters – Roze, Lūcija and Marija.  Each sister built a new castle on the land which she inherited – Roze built Rēzekne, Lūcija built Ludza, and Marija built Viļaka.  A memorial plaque at the foot of Mākoņkalns hill recalls the visit which pre-war Latvian President Kārlis Ulmanis paid to Latgale in 1938.

One of the most important military and political elements of the Livonian Order, the Bauska Castle was built between 1443 and 1456 at the place where the Mūsa and Mēmele rivers flow together.  The castle had five towers and walls that were up to three metres thick.  Between 1580 and 1596, the forecastle was replaced with a residence for the duke of Courland, and its walls were finished with the sgrafito technique.  The castle suffered damage during wars in the 16th and 17th century, but it was always restored until 1706, when the Russian military blew it up during the Great Northern War.  Today the castle houses a museum, with a viewing platform in its south-eastern tower.

The Krimulda Estate was first recorded in documents in the 15th century.  The Krimulda Castle that can be seen now is on the right bank of the ancient Gauja River valley opposite the aerial tram.  There are outstanding views of the ancient river valley from the castle and the opposite shore.  The Krimulda Castle is a Neo-Classical structure which was built by a local nobleman in the 19th century.  In the 1920s, the castle was expropriated and turned over to the Latvian Red Cross, which installed a children's sanatorium there.  Today the Krimulda rehabilitation hospital is in the building, and among other structures, the ones that have survived include the stables, threshing barn, servants' quarters, governor's quarters, and the so-called Swiss house.  Educational tours are available, and overnight stays are possible at the estate.
