It is exciting for tourists to learn about castles and churches in the country they are visiting since they are one of the tourists’ favorite activities. Let’s take a look at Slovenia’s architecture and some of the most famous and beautiful castles and churches in the country.
Which Are The Most Beautiful Castles in Slovenia?
Slovenia is rich in history, and part of this history includes the 500 castles built between the medieval period, the Renaissance, and the Baroque period. You can also find ruins of fortresses that started being made during the antiquity.
Many castles are now in ruins. However, some of them are still used every day and are very popular among tourists. In numerous castles, you can see exhibitions, visit museums, see concerts, watch movies, dine, play games, or even get married.
In some Slovenian castles and manors, you can even stay for the night, such as the Otočec Castle, the Lambergh Château & Hotel, the Kenda Manor, the Mokrice Castle, or the Strmol Castle. It is the perfect way to spend a magical, romantic, and unforgettable night in Slovenia.
To discover the fairytales that are Slovenian castles, let’s take a look at three of Slovenia’s most famous castles.
Ljubljana Castle

The Ljubljana Castle stands in the city-center of the Slovenian capital, on top of a hill. The Castle has a rich and complex history. It was a medieval stronghold since the 15th century, a prison owned by Fascist Italy during the occupation of Slovenia during World War II.
Besides its fascinating story, the Castle is also a fantastic viewpoint of the city of Ljubljana. You can climb up the hill in 15 minutes from the city center if you do not mind walking up. Otherwise, there is a funicular going right to the Castle. You can also join the Castle from the back of the park, passing in front of one of the oldest vineyards and unique viewpoints.
The Castle in itself is not particularly impressive inside. It seems more imposing from the city. It still is nice to go if you have a bit of time. There is a staircase on the right that you can use to see the city without paying. However, to go on top of the tower, you will need to pay, which is not necessarily worth it.
We advise you to stop at the cafe to enjoy a fresh drink during the summer. You can also visit the little chapel of the Castle, and take a photo with the flower heart in the castle courtyard. If you are a fan of games, you can also try the Castle’s escape room for 13,00 € per adult.

The Bled Castle, or Blejski Gard, is more impressive from the lake than once you are inside it. It is not necessary to visit it unless you are a huge fan of castles. However, it is mesmerizing from down the hill, especially in the evening when it is lit up.
We do not know precisely when the Bled Castle was built. However, we know it was around the year 1000, after the German king Henry II ceded the Bled estate ownership to the Bishop of Brixen.

Which Are The Most Beautiful Sacred Monuments in Slovenia?

Although Slovenians are not particularly religious, the country is filled with Catholic religious buildings, which are the leading and almost only religions in the country. In 2017, nearly 60% of Slovenes declared themselves Roman Catholic, 2,4% are Muslim, 2,3% are Orthodox Christians, and about 10% are atheists.
The Christian religion came to Slovenia during the 8th century when the Slavic tribes living in the area embraced it as their new religion. It stayed an essential religion in the country until 1945, when industrialization and capitalism caused a decrease in religious beliefs.
Among the branches of Christianity present in Slovenia, the most important is Roman Catholic, followed by Protestantism, especially in the Prekmurje region.
In Slovenia, you will find a Catholic church in almost every town and at every corner. You will also encounter a significant number of monasteries and convents.
The oldest churches you will find were built in late antiquity, and you can still visit their remains in Ljubljana, Ajdov Gradec, or near Kobarid.
You could even decide to go for a pilgrimage at the Basilica of Mary Help of Christians. Many tourists also love to ring the wishing bells on the Bled lake island, where is located a lovely church. Legend says, if you ring the bell three times, your wishes will come true.
Among the most beautiful churches to visit in Slovenia, here is a quick list of the ones you must see:
- Basilica of the Virgin Protectress in Ptujska Gora
