A delightfully-accessible 13th-century fortress that now lies in ruins above Bosanska Krupa, this should be your first stop when in town. There isn’t a huge amount to see within the ruins (they are ruins, after all), but that intangible sense of history that only decrepitude can create is most certainly here. The views are stunning too, extending over both side of the city with the rivers playing a starring role. The fortress was originally in Croatian hands, although it eventually fell to the Ottomans in the 16th century, at which point the town began to grow. The Ottomans were sure to keep this spot well-stocked, as it was an important stronghold for their ambitions to spread west, although it never really worked out for them in that respect. This is history, intangible history, with added beauty.
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
