When traveling to Malta, make sure you visit Mdina - one of the oldest cities of this small, but so picturesque country. It is actually here where 4000 years back was the former capital of Malta. Being called by Maltese and visitors the "Silent City" it still preserves a relaxing, and peaceful atmosphere due to the absence of cars, narrow sidewalks, and fortification walls, which till nowadays seem to protect the city from some invisible danger.
Once you make your first steps through the main gates of this beautiful city, you will immediately stumble upon an impressive arch construction made in baroque style. This is the entrance to National Museum of Natural History, which is housed in a French Baroque palace. Due to festivities held in the city on that day (about which I will tell you in more detail bellow), workshops, and representative scenes of the traditional Maltese crafts were organized in the courtyard of the museum. The participants of the workshops were even dressed in traditional Maltese costumes, so you were literally transposed into the past, witnessing all the secrets of arts, and crafts inherited by the locals throughout the course of hundreds of years.
Walking towards the very center of Mdina you will see this impressive building, which is the Cathedral Museum of the city. It displays to the public a collection of historical artifacts of great importance, including works of such artists as Rembrandt, and Albrecht Durer.
The 17th-century Cathedral dedicated to St. Paul- the patron saint of Malta is located in the very center of the city. The impressive Baroque façade of the cathedral is just a foretaste of what's hidden inside. The moment when you find yourself inside it, you are literally dazzled by the amount of marble, and decorations you can see there.
Now let me tell you a bit more about the actual festivity which was held in Mdina. It is called the Medieval Mdina festival, and it is organised every year at the end of April. During this festival the whole city of Mdina is taken over by different kinds of performances, workshops, mini-scenes imitating events and situations from medieval times, markets, and much more. This offers you the opportunity to explore in depth the city, its culture, traditions, and history.
Here's a small, but quite impressive church, which I would recommend to include in your list when visiting Mdina. It is called St. Roque's Chapel, aka Our Lady of Light.
