What to Expect When Visiting the Crypt of St Mary Magdalene

The experience begins in the stunning Baroque interior of the Church of St. Mary Magdalene. Designed by Kilian Ignaz Dientzenhofer, the church itself is a masterpiece of light and space. Once you descend into the crypt, the atmosphere changes instantly. The air becomes cooler, and the sound of the bustling town fades away.

Inside, you will find the original foundations of the church, which were built on thermal spring deposits. The guide often explains how the hot water and steam influenced the construction. You will see the remains of an old cemetery and an ossuary containing human bones. It is a somber but deeply historical environment that feels worlds away from the luxury spas nearby.

The tour is guided and usually lasts about 30 to 45 minutes. You will see unique altars made of thermal sinter and learn about the structural challenges of building on volcanic ground.

Practical Details: Costs, Timing, and Booking Tips

Visiting the crypt of St Mary Magdalene requires a separate ticket from the main church entrance. In 2026, prices typically range from 100 to 150 CZK for adults. Discounts are usually available for students, seniors, and families. It is best to check the Karlovy Vary Official Tourism site for the most current seasonal hours.

Tours do not run constantly, so timing is everything. They usually start on the hour or half-hour during the peak summer season. In the winter months, the schedule is much more limited. We recommend arriving at least 15 minutes early to secure your spot in a tour group. Groups are kept small to ensure everyone can see the narrow passages clearly.

You can often book tickets directly at the church entrance. However, if you are visiting during a major festival, pre-booking is wise. The crypt is located right next to the Vřídlo (Sprudel) colonnade, making it easy to fit into a colonnades walking tour. Wear comfortable shoes as the ground can be uneven and slightly damp.

Pros and Cons of the Crypt Experience

Every attraction has its highlights and drawbacks. This crypt is no exception, and your enjoyment will depend on your interests. Here is a quick breakdown of what to expect during your visit.

• Pros: Unique geological foundations, impressive ossuary, and a cool escape from the summer heat.
• Cons: Limited accessibility for wheelchairs, short tour duration, and potentially spooky for young children.

Best for: History buffs, fans of Baroque architecture, and travelers interested in "dark tourism" or ossuaries. It is a great way to see a different side of Karlovy Vary beyond the spas.

Skip if: You suffer from claustrophobia or have significant mobility issues. The stairs are steep and the passages can feel tight. If you want a more comprehensive city overview, see our Karlovy Vary sightseeing guide instead.

Who Should Go and Who Should Skip This Attraction?

This attraction is a must-see for anyone interested in the technical side of historical construction. Seeing how 18th-century builders handled the pressure of thermal springs is fascinating. It is also ideal for those who enjoy the quiet, reflective nature of religious sites. The Visit Czechia board often highlights this as a key cultural stop.

Families with very young children might find the experience a bit difficult. The environment is dark and quiet, which can be challenging for toddlers. Additionally, the presence of human remains in the ossuary may require some explanation for older children. If you are traveling with a family, consider the funicular ride instead.

For solo travelers and couples, the crypt offers a peaceful break from the crowded colonnades. It provides a deep sense of time and place that you won't find at the modern spa hotels. If you are planning a full day, you might also enjoy attending one of the concerts in St Mary Magdalene Church after your crypt tour.
