Kruja is one of the most mentioned cities in the Albanian history. Kruja lies on the slope of the Kruja mountain, at an altitude of 608 m above sea level. The name and the importance of the city are closely related to the 25 years of activity of our national hero, Skanderbeg, who in the fifteenth century made Kruja a bastion of uncompromising resistance against the Ottoman. Kruja has a long list of attractions to offer tourists from the ancient castle nestled in the craggy rocks, two museums, stunning views, a nearby national park, sacred temples, natural springs, the ancient city ruins of Albanopolis, and the old bazaar. The Gjergj Kastrioti Skanderbeg Museum is situated inside the castle walls, which date back to the fifth and sixth centuries A.D. The museum itself was inaugurated in 1981. Within the walls of the castle are also the Ethnographic Museum and the Dollma Tekke.

The Sari Salltiku Mosque is a mosque in the city of Kruja. It was built in honor of Sari Salltiku, who was a cleric of the Bektashi faith. Sari Salltiku is said to have left his mark in Kruja around the 1300s. A friend of Sultan Bayazit, he was also a disciple of Ahmed Jeseviut. The saint's footprint is located in the mosque at the entrance of Kruja. In 1967, the communist regime demolished this mosque, along with other religious sites across Albania. The Sari Salltiku Mosque was reconstructed in 1991. The holy cave in the Kruja mountain holds many mysteries. Paranormal stories date back to 1325 when Sari Salltiku arrived from Turkey, sent by Haxhi Bektesh Veliu, to practice religious rites away from people.
