Finland is a country "nourished" by water, and the blue of the Baltic Sea guards her, the star

The large and small lakes are full of her, and the reputation of "the land of a thousand lakes" can only give birth to sincere envy when she is there.

Water has shaped the Finnish way of life to a large extent, whether in the silent lakes or in the mast-lined Gulf of Finland, you can see many yachts, and even on the road, you will see private cars towing private yachts passing by from time to time.

Many hotels and estates in Finland are also located near the water, from Haikko Manor in Porvoo to Bear's Den, which is tucked away in the depths of Rovaniemi.

On a sunny afternoon, on the lawn and under the canopy of trees, there are Finns reading and drinking tea leisurely

When the Finns "cut down one tree and plant three trees", we understand God's preference for Finland.

If you have time in Finland, you can't go without a visit to Suomenlinna.

Suomenlinna is a masterpiece of Okosteen's design, built on a string of small islands off the coast of Helsinki. Built more than 250 years ago, it is one of the largest surviving coastal defense military fortresses in the world and one of Finland's most important and famous attractions.

Finnish castles also have churches, barracks, city gates and other places of interest, and there are some of the world's rare maritime military relics, and in 1991 Finnish castles were included in the UNESCO World Heritage List and protected.

Suomenlinna is located on the three islands south of Helsinki: Big Black Island, Little Black Island and Wolf Island, and is an ancient coastal defense fortress that regulates the sea route from the Gulf of Finland to Helsinki.

The intact remains of the fortress are included in the UNESCO World Heritage List. There are 10 museums on the island, including the Coastal Fort Museum, the Wesco Submarine Museum, and the Doll & Toy Museum.

Suomenlinna is open all year round and ferries run to different times. Suomenlinna was built more than 250 years ago and was designed by a Swedish artillery officer, Okostin. The famous Suomenlinna is the world's largest surviving maritime fortress and a World Heritage Site. It is a building on a number of small islands off the coast of Helsinki and is a product of the Swedish era.

To this day, the forts, castles, and barracks of the past have been well preserved. Today, hundreds of years later, Suomenlinna has evolved into a stylish meeting place. The Imperial Gate is the symbol of Suomenlinna and was built for military parades between 1753 and 1754.

In 1752, when the founder, King Adolffredrik of Sweden, came to inspect the project, the place where the ship anchored was the location of the Emperor's Gate. Built in 1852, Helsinki Cathedral is the quintessence of Finnish art history with its exquisite white exterior and extraordinary atmosphere.

At the top of the cathedral is a bell tower with pale green arches, which rises more than 80 meters above sea level, making it a landmark of Helsinki. Helsinki Cathedral is Finland's most popular place to get married.

The forts, castles, and barracks built by the Swedes on the island 250 years ago have been well preserved.

There are dozens of museums as well as restaurants and cafes on the island. The Finnish Castle Museum offers three types of locally brewed beers from Finnish castles with a pure and unique taste. The island's dockyard uses traditional techniques to build an old sailing ship, and visitors can also take part in it.

On the Imperial Gate in Suomenlinna, a marble slab is engraved with the motto of Augustin Erlenschwald: "Descendants, stand here on your own strength and do not rely on the help of foreigners." ”

This adage is really special enough to have a backbone.

Suomenlinna was designed by a Swedish artillery officer, Okostin. He died in 1772 after building a chain of defensive castles on a series of islands near Helsinki, and it was not until the end of the 18th century that the design of Suomenlinna was finally completed.

At that time, the Russians were eyeing Finland under Swedish rule.

At that time, the Russians not only relied on Kronstadt, which was strategically important in the eastern Baltic Sea, to protect its central city of St. Petersburg, but also used it as a base camp and supply base for the Russian fleet to fight against the Swedish maritime forces, posing a serious threat to Finland.

One of the main reasons for Okostien's construction of Suomenlinna at that time was to defend against Russian invasion of Finland.

When Finland was still part of Sweden, the Stockholm parliament decided to build a military castle on a small island outside Helsinki and named it Swedenborg.

In 1748, thirty-five-year-old Augustin Ehrensvärd, a Swedish artillery officer, began the design program for Suomenlinna.

Okosteen was born into an aristocratic family and had a good family background.

Initially, he planned to build a chain of defensive castles on a series of islands near Helsinki, and then to strengthen and consolidate defensive combat capabilities in strategically important cities in his country.

The first step in the plan was to build a chain defense castle, Suomenlinna was a masterpiece of Okostin's design, but in 1772, the year of Okostin's death, only the first phase of the basic construction of the chain defense castle was completed.

However, to his regret, the second step of the design plan was not implemented at all during his lifetime. It was not until the end of the 18th century that the design project of Suomenlinna was finally completed. At that time, the Russians stationed their main military forces in Kronstadt, near Finland, and under the command of Peter the Great, eyed Finland under Swedish rule.

Kronstadt was also strategically important in the eastern Baltic Sea, as the Russians could rely on it not only to protect their central city of St. Petersburg, but also to serve as a base camp and supply base for the Russian fleet in the fight against the Swedish maritime forces.

In 1854, when Russia fought against the British, French and Ottoman Empires, the famous "Crimen AR" broke out.

Later, as Sweden's military power declined year by year and the Russian Empire grew stronger, the Swedish troops stationed in Suomenlinna surrendered to Russia in 1808. In 1917, the October Revolution in Russia triggered Finland's independence.

After Finland's independence in 1918, the Finns reclaimed the castle and named it Suomenlinna (Suomenlinna's Swedish name is still "Swedenborg"), and in 1918, as a result of the revolution in Finland, there were fierce large-scale clashes between radical and conservative parties, and many members of radical parties were arrested after defeat and imprisoned in Suomenlinna, during which many died of malnutrition and disease due to the harsh conditions.

In 1919, Finland officially sent its own troops to Suomenlinna. With the end of the castle's military age, the castle was taken over by the Finnish Ministry of Culture in 1973 and later converted into a museum.

Renovated three times in 1927, 1976 and 1987, the magnificent Finnish Castle covers an area of 80 hectares, including 8 kilometres of walls, 105 cannons, 290 engine rooms and a series of well-known museums......

These include the Finnish Castle Museum, which presents the history and construction of the Walled City, the Alan White Museum, which exhibits artifacts from the Swedish period, the Toy Museum, which collects old toys from the 19th century, the Maneki Military Museum, which exhibits former armaments, the Visgau Submarine Museum, the Coastal Cannon Museum, which exhibits the castle's heavy artillery from different eras, and the Customs Museum, which details the work and history of the old customs.

The Finnish Castle Museum offers three types of locally brewed beers from Finnish castles: "Finnish Castle Glory", "Finnish Castle Party" and "Helsinki Porter". The shipyard on the island has built an old sailing ship using traditional techniques.

During the war, Suomenlinna was an important military fortress for coastal defense and occupied a crucial military position in Finland's War of Independence and Liberation. During the Finnish Civil Revolution, there were fierce large-scale clashes between radical and conservative parties, many members of radical parties were arrested after defeat, and Suomenlinna was used for imprisonment.

In peacetime, well-preserved places of interest such as forts, castles, military barracks and so on brought tourism to the Finnish people. In 1991, Suomenlinna was declared a UNESCO World Heritage Site.

Suomenlinna is no longer filled with the smoke and bloodshed of war, and has become a holy place for people to visit, recuperate and live.

It has played an indelible role in the economic development of Finland.

Finnish castles also have churches, barracks, city gates and other places of interest. In order to take care of the needs of tourists

The castle has nine restaurants and cafés, a visitor information centre and, as described by UNESCO, Finland has one of the world's most complete maritime military monuments.

In 1991, Suomenlinna was declared a UNESCO World Heritage Site, and today Suomenlinna is no longer filled with the smoke and bloodshed of war, but has become a popular tourist and healing destination.
