An impressive set of military structures between the Baltic Sea and Lake Liepāja and Lake Tosmare.  Construction of the fortress began in the late 19th century on the basis of a decree by Russian Tsar Alexander III, and it cost 45 million gold roubles.  The fortress includes accommodations and elements of fortifications – sites for cannons, trenches, gunpowder cellars, systems of canals, a narrow-gauge rail line, etc.  In 1908, the fortress was shut down because of a change in Russia’s defence concept, and the construction of it was declared to have been a strategic mistake.  There were attempts to blow up the underground structures and cellars during World War I, but that did not really succeed.  Some elements of the fortress were of great importance in Latvia’s liberation battles.  Surviving today are the Northern forts, the Central fort, the Eastern fort, the Southern fort, the shoreline defensive batteries (No. 23, 3), Redāns, Lunete, and others.  Most are not improved, so visits may be dangerous.  The northern part of the fortress includes the Military Port, which has experienced seven different armies and regimes. During the Soviet years, it was closed to civilians.  There are many outstanding monuments to military history.  Tourists love the Karosta prison, which offers educational programmes.

The first Dnyestr-M radar station was opened here in 1969 to calculate the trajectories of ballistic missiles. The trajectories of satellites were also calculated here. The range of the radar station was 5,000 km. In 1972, construction began on a second, more modern radar, the Dnyepr-M. In 1977, it was ready for use, and the first radar was modernised at the same time. The two radars were located in buildings that were 250 m long and 17 m high. During a 24/hour period, they could identify the height, speed and flight trajectory of up to 750 space objects. In 1985, work began on a third, even more modern radar – the Daryal-YM. This was a radar that could “peek” across the horizon. The antenna building was 117 m high (19 stories), 80 m long and 80 m wide. It had a planned range of 6,000 km, but it was not completed. After the withdrawal of the Russian army in 1995, the building was blown up. That cost LVL 6,172,311 and used up 360 kg of explosives. The territory of the radar stations took up 1,072 hectares, with barracks, a hotel, 551 apartments, a medical facility, a water tower, a war hospital, a bomb shelter, etc. The aim of the facility was to monitor space above Western Europe and North America, as well as to “intercept” any ballistic missiles that were fired at the USSR. The territory is closed to visitors, but it is an important part of Latvia’s military heritage. The abandoned territory can be viewed from the outside. The nearby bus stop is called “Kombināts.” This was the only facility of its kind in the Baltic States.

!!! Since March 2018 the Skrunda army base is closed for visitors.

Ezeres kultūrvēstures un novadpētniecības materiālu krātuve “Muitas nams” ir izveidota vēsturiski nozīmīgā ēkā, kur, II pasaules kara noslēgumam tuvojoties, 1945. gada 8. maijā tika parakstīts  Kurzemes katlā ielenkto vācu karaspēka daļu kapitulācijas akts. Ar to tiek uzskatīts, ka Ezerē faktiski beidzies II pasaules karš.

Krātuves materiālu ekspozīcijas ir no Ezeres pagasta senvēstures līdz šodienai, tai skaitā ezernieku vaļasprieki.
