Our journey through medieval Sweden begins with two of the most important royal residences - Stockholm Royal Castle and Kalmar Castle. These two buildings, although different in history and architecture, are the foundations of Swedish statehood and witnessed the most important events in the country's history.

Stockholm Royal Castle, also known as Stockholms slott, is an imposing structure in the heart of the Swedish capital. Although the castle's current form dates mainly from the 18th century, its history dates back to the Middle Ages. The castle is the official residence of the Swedish royal family and also a popular tourist attraction. Visitors can admire the beautiful royal apartments, the throne room and the armory. Of particular note is the Three Crowns Museum, which presents the history of the castle and the Swedish monarchy.

The castle is open to the public year-round, and tickets can be purchased on site or online. Ticket prices range from 160 SEK for adults to 80 SEK for children and teenagers (as of 2023). It is worth planning at least 2-3 hours for the tour to fully appreciate the rich history and architecture of the place.

Kalmar Castle, on the east coast of Sweden, on the other hand, is one of the best-preserved Renaissance castles in Northern Europe. Its history dates back to the 12th century, when the first defensive tower was erected. The castle played a key role in Swedish history - it was here that the Kalmar Union was signed in 1397, uniting Sweden, Denmark and Norway under one sceptre.

Kalmar Castle impresses with its architecture, combining elements of a medieval fortress with a Renaissance palace. Visitors can admire the royal apartments, the castle chapel and the massive fortress walls. Of particular interest is the opportunity to see traces of the Polish presence in the castle - in 1598 it was briefly in the hands of the troops of the Republic during the expedition of Sigismund III Vasa.

The castle is open to tourists all year round, with extended opening hours during the summer season. Ticket prices are about 150 SEK for adults and 80 SEK for children (as of 2023). During the summer season, special activities are organized for families with children, such as knight workshops and historical shows.

Comparing the two castles, it's worth noting that Stockholm's Royal Castle offers more luxurious and baroque interiors, while Kalmar Castle impresses with its medieval atmosphere and picturesque location by the sea. Both places are well suited for visiting with children, offering interactive exhibitions and educational programs. Kalmar Castle can be a bit less crowded than its Stockholm counterpart, which can be an advantage for families looking for a quieter visit.

Continuing our tour of medieval Sweden, we move on to two impressive fortresses that combine defensive functions with royal splendor - Gripsholm and Örebro castles. These two structures, although different in location and history, are excellent examples of Swedish defense and palace architecture.

Gripsholm Castle, picturesquely located on Lake Mälaren in Mariefred, is one of the best-preserved Renaissance castles in Sweden. Its history dates back to the 14th century, but it owes its present shape mainly to a rebuilding commissioned by King Gustav I Vasa in the 16th century. Gripsholm Castle is best known for its National Portrait Gallery, which contains more than 4,000 portraits of Swedish personalities from the 16th century to the present.

Visitors to Gripsholm can enjoy not only the impressive castle halls, but also unique interiors, such as the 16th century castle theater - one of the oldest surviving theaters in Europe. The castle is surrounded by a beautiful park, ideal for family walks and picnics. There are special tours for children with educational games and activities.

The castle is open to the public from May to September, and tickets cost about SEK 140 for adults and SEK 70 for children (as of 2023). It's worth planning a full-day tour to fully enjoy the atmosphere of the castle and its surroundings.

Örebro Castle, on the other hand, located in the center of the town of the same name, is an impressive example of medieval defensive architecture. Its history dates back to the 13th century, when the first defensive tower was erected. Over the centuries, the castle was expanded and modernized, becoming one of the most important fortresses in central Sweden.

Örebro Castle impresses with its massive body and distinctive towers. Visitors can explore the dark dungeons, climb the defensive towers and admire the royal chambers. Of particular interest is the castle's history related to the imprisonment here of Sweden's future King Eric XIV.

The castle offers a variety of attractions for families with children, including interactive historical exhibitions and medieval craft workshops. During the summer season, knight shows and early music concerts are held in the castle courtyard.

Örebro Castle is open to the public year-round, with extended opening hours during the summer season. Ticket prices are about SEK 130 for adults and SEK 65 for children (as of 2023).

Comparing the two castles, it's worth noting that Gripsholm offers a more refined Renaissance atmosphere and is of particular interest to art lovers because of its National Portrait Gallery. Örebro Castle, on the other hand, impresses with its medieval austerity and is ideal for families looking for a more interactive historical experience. Both castles are perfectly suited for visiting with children, offering special educational programs and attractions for the little ones.

At the end of our tour of Sweden's medieval sights, we move on to Gothenburg, where a unique site awaits us - the Kronan Open Air Museum. This 17th-century fortification, although not a typical castle, is a fascinating example of Swedish defensive architecture and offers unforgettable views of the city.

Skansen Kronan was built between 1687 and 1700 as part of Gothenburg's defense system. Its name means 'Fort of the Crown' and refers to the crown that once adorned the top of the structure. The fortress was designed by prominent Swedish military architect Erik Dahlbergh and was meant to protect the city from potential Danish attacks.

What sets Skansen Kronan apart from other defensive structures is its location on Skansberget Hill in the center of Gothenburg. As a result, the fortification offers not only a history lesson, but also breathtaking views of the entire city and harbor. It is the perfect place for families who want to combine history lessons with outdoor activities.

While visiting the Kronan Open Air Museum, you can admire the massive defensive walls, explore the interior of the fort and climb to the observation deck. Inside there is a small museum presenting the history of the structure and its role in the defense of Gothenburg. Children may find the exhibits related to the daily life of the soldiers stationed at the fort particularly interesting.

It is worth noting that, unlike many other historical sites, the Kronan Open Air Museum has never been used in warfare. Paradoxically, its powerful construction and strategic location effectively deterred potential aggressors, making it a symbol of peace and security for the city.

The Kronan open-air museum is open to the public all year round, and admission to the fort is free. Various cultural events, concerts and picnics are held here during the summer season, making it a popular gathering place for tourists and Gothenburg residents alike.

Comparing Skansen Kronan with the previously discussed castles, it is worth noting its unique character. While Stockholm's Royal Castle or Kalmar Castle offer a more traditional sightseeing experience, Skansen Kronan allows for more casual exploration and active recreation. It is an ideal place for families with children, who can run, climb and explore history here in a more informal way.

To sum up our tour of Sweden's medieval monuments, it's worth noting how diverse the sites are. From luxurious royal residences to massive defensive fortresses to unique urban fortifications, each site offers a different experience and perspective on Swedish history. Whether you're a history enthusiast or a family looking for interesting attractions, the medieval sights of Sweden will certainly not disappoint you. Remember that by visiting these places, you not only learn about history, but also become a part of it, adding your chapter to the centuries-old history of these remarkable buildings.
