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.
