Only recently opened to the public, Mysterium Fidei is ‘hidden’ away on a quiet corner on St Christopher Street and Strait Street.
Visitors often stumble upon our door whilst exploring Valletta.
Often, simply curious to see what lies behind the walls of the Monastery, visitors are then immersed into the fascinating history whilst appreciating the architecture and experiencing the quiet serenity of the cloisters. Visitors can see how the nuns lived, in a totally authentic setting.
Cloistered nuns lived a life closed off from the outside world so they had to be self sufficient. Even until today the chickens lay eggs and fruit and vegetables are grown in the garden.
Built with self sustainability in mind there are seven wells dotted around the monastery. Rainwater is collected from the roofs.
Mimi the monastery cat, often welcomes visitors personally and happily walks around listening to the audio tour before finding a sunny spot in the garden providing a popular photo opportunity.
Infants and small children can ride in a pram or stroller

Mysterium Fidei
Mysterium Fidei is a multi sensory experience located within St Catherine’s Monastery, in the heart of Valletta. The door to the Secret Garden has been closed to the public for over 400 years, it is now open for you to enter this tranquil space and take a glimpse into the lives of the cloistered nuns. When joining the monastery, the nuns took vows never to leave. They lived a self-sustainable life closed away from the outside world. You can see the original, authentic kitchens, bedrooms, washrooms and even visit the crypt, their final resting place. The enclosed garden is a rarity in Valletta, here you can escape the hustle and bustle of the busy Valletta streets and experience the peace and serenity of this hidden oasis. Mysterium Fidei is a unique, must see, experience. It gives visitors the opportunity to learn the history, appreciate the architecture, enjoy the peaceful surroundings and contemplate the lives of the women who chose the life of the cloistered nun.

The staff on duty were very welcoming and showed a great deal of empathy when I told them the reasons for my visit. Namely, that I had lost my sister Catherine to Cancer and so wanted to quietly remember her at The Monastery of Saint Catherine whilst on my visit to Malta. The Secret Garden is truly an Oasis in the midst of the business and buzz of Valetta. If anyone wants a quiet, cool and contemplative space whilst on Malta, St Catherine's is the place to go.

Amazing place, very calm, great experience. Interesting history behind. Good to see the "secret garden" and the rooms where the nums were installed in the past... Well received by the recepcionista. Great place to recover the peace. It is surprising to see such a calm place in the middle of a very active city.

An extremely interesting and thoroughly worthwhile experience. The various rooms are laid out well with lots of information on the activities carried out in them and the secret garden is not to be missed. Staff are very friendly and knowledgeable.

My wife and I visited the Mysterium Fidei Museum in Valletta during a recent holiday, and it was well worth doing. Its a very relaxing and peaceful experience, and it's great how they have managed to bring the place to life. A visit won't last much longer than an hour, but the entrance price reflects this and represents good value. Highly recommended.

This place was creepy. Like- deeply creepy. I would not go back and would not recommend it. The control rooms are so gross- and the fact that this place was a female orphanage while the nuns would do these practices on little girls makes it extra creepy.

8 Euros very well spent! My wife and I visited today and loved it. It felt like a wonderful privilege to be allowed a glimpse of life in a closed order - of where and how the nuns, lived and worked. We were also extremely lucky to have met Manuel, who was extraordinarily generous in showing us around and answering our questions. Manuel, we wish you, your sister and the community all the very best and especially all best wishes for a continued life for the community for the future. Noel & Suzy Hanchard
