The Bauska Castle contains a collection of cast iron cannons which date back to the latter half of the 17th century and the beginning of the 18th century. They were manufactured in the Duchy of Courland. The cannons that are in the garden of the castle were not found there – they were found in different locations in Zemgale. Four of the largest cannons came from Jaunsvirlauka, where they were found on the banks of the Lielupe River opposite Emburga. They are the best preserved weapons of their type in Latvia. The only cannon that was found in the castle itself is currently in its South-eastern tower as a thematic exhibit. When it was being cleaned, two cannonballs were found in the weapons. The local Livonian Order castle is in ruins, but it and its defensive structures, including earthen ramparts that were installed from the mid-15th until the early 18th century, represent an important element of Latvia’s military heritage.

There are several partly preserved buildings here, but there is a lack of information as to what they were used for. The reason why the buildings are in such sad shape is that people have removed parts of them to use as building materials.

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.

Liepene, in the Ventspils District, was once home to a coast guard division. The facilities are now privately owned and offer accommodations to tourists.

Until the 1680s, where the Vecdaugava neighbourhood is located, there was a castle which, because of natural changes in the riverbed of the Daugava, was then dismantled and “moved” to the Left Bank of the Daugava. Nothing remains of the castle, but people can still see the remnants of old barriers and moats. Swedish soldiers used the facility at the beginning of the Great Northern War. The place is certainly interesting in the context of Rīga’s history and military heritage, and if you’re in the northern reaches of the city, we recommend that you go and have a look.

This facility was used in the past by communications officers, and it was also a training centre. The Ventspils Home Guard Battalion is housed here at this time. The facility is not open to civilians. Along the road there are metal structures which show where the entrance to the facility was once located.

Forts were built and rebuilt at this location for many centuries by Germans, Swedes and Russians. In 1912, several forts were erected at Mangaļsala and Bolderāja. There were two forts with 254-mm cannons, six with 152-mm cannons, and three with 138-mm cannons. Each fort had two cannons.

The zenith missile brigade and its communications headquarters were used for the provision, planning and co-ordination of radio communications. The object is all but abandoned, but it is owned by the Latvian Repatriation Centre and the Christian Mission.

Today it seems unbelievable that just 20 years ago there were buildings on the coastline with massive projectors that were rolled onto a platform at night so as to shed light on the nearby sea and beach and to look for potential violators of the border regime. Only the buildings and the ruins of the platform are still there – they have been seriously damaged by the waves of the sea.

The so-called Comet Fort was built on the Left Bank of the Daugava at its mouth, not far from the present Daugavgrīva lighthouse. It was built around the same time as the other forts of Mangaļsala (around 1808, although some sources say 1788). There were four Kane-type 152-mm cannons. The defensive batteries at Komētforts and Mangaļsala repelled a British naval attack in the Daugava estuary in 1855. It has to be added that Komētforts is a cultural monument of local importance. If we go along the shore of the sea from the Daugavgrīva nature reserve toward the Daugavgrīva lighthouse and scale the frontal dunes (without going past the sign which says “Closed Territory. Border Zone.”), then we can see the positions of the cannons, as well as underground cellars where munitions were once stored. The territory starts approximately 500 metres before the Daugavgrīva lighthouse and stretches to the lighthouse itself. During Soviet times, the territory was closed to civilians, because many secret military objects were in this area and in Bolderāja.
