Old town Ljubljana (Castrum Liube) was built in the medeieval ages. It was the seat of the Templars and later it was the seat of Hospitaller order. The town was first mentioned in the documents of Duke Andrija where it was called Castrum Gliube. At some point it came under the rule of Croatian-Hungarian rulers. During the fight for the power between kings Ladislaus of Naples and Sigismund, Liuba was captured by the captain Alojzije Aldemarisko from Naples.
King Ladislaus was very gratefull for the help, during that war, that he got from brothers Matafar fom Zadar. That is the reason why he gave Liuba to them as a present. At the begining of 16th century Liuba was a strategic point for the Venice, especially during the Turk attacks. Rich city life lasted untill the end of the 17th century, untill the end of the Ottoman threat. Then the city was abandoned because Venice no longer needed it for defence. The few material remains are enough to visualize the whole fortress system. The remains of two churches can be seen there today, the church of St Marija and the church of St Marcela. Gothic church of St Marcela is the best preserved building within the ruins of the city. The most valuable thing that was preserved is a golden chalice which has been kept in the church of St Martin in Ljubač. The foundations are all what remained from church of St Marija.
Today, the size of the Castrum within the defensive wall is around one hectare. It was bigger in the medieval time, but it became smaller during the time. The defensive wall is the most preserved from the east side. The tower that was protecting the entrance is semicircular shape from the outside with walls 1,5m thick. On the north side there are remains of the smaller square tower. From the tower to the north and north east the remains of a thick wall that goes down the slope can be followed
