Alexandru Lăpușneanu subsequently moved the capital to Iași in 1565 and so the castle lost its status and consequently fell into a long period of decay. Although it has never been conquered by its invaders, regardless from where they stemmed, the castle was destroyed Dumitrașcu Cantacuzino. Following its destruction, it was abandoned for approximately 300 years.

After the northern highlands of the former medieval Principality of Moldavia were annexed by the Habsburg monarchy following the Treaty of Küçük Kaynarca during the late 18th century and became henceforth known as Bukovina (German: Bukowina or Buchenland), the castle was eventually repaired by Austrian architect Karl Adolf Romstorfer, who raised its defensive walls from ruin and also worked on its keep during the late 19th century and early 20th century.

During the late 20th century, more specifically throughout the 1960s (i.e. in communism), there have also been a series of restoration and consolidation works carried out on the surface of the castle.

The heraldic symbols on display in the castle pertain to the Moldavian nobility of the Late Middle Ages (Romanian: Evul Mediu târziu), more specifically to the Moldavian rulers. The most common heraldry is the coat of arms of Stephen III the Great (who was also given the title Athleta Christi by Pope Sixtus IV for defending Europe against the Ottoman Turks at the Battle of Vaslui in 1475).

The castle disposes of entertaining digital facilities that enable a real-time simulation of the outfits of its visitors into medieval costumes, ascribing them a medieval title in the process (e.g. soldier or merchant).

The castle can be visited both in the inner courtyard, in the main keep, in the cellars, in the throne room, and on the surrounding defensive walls.

The Medieval Seat Fortress of Suceava is located on the eastern ridge of the town of Suceava, overlooking the town. It was constructed on a plateau that rises 70 metres above the river meadow of Suceava (Romanian: Lunca Sucevei). It is surrounded by trees on all sides and by a nearby forest both to the west and east.

Aside from its tourist attraction and historical statuses, the Medieval Seat Fortress of Suceava had also been the site of a yearly rock music festival entitled Bucovina Rock Castle in the recent past, a festival where both national and international rock artists and bands performed. A major international rock artist who had performed at the Bucovina Rock Castle was Dutch jazz fusion and progressive rock guitarist Jan Akkerman of Focus in 2015.

On a yearly basis, the Ștefan cel Mare medieval art festival is held in the fortress. The festival consists of jousts, pyrotechnic and laser shows, medieval singing and dancing, fight scenes, drama plays for children, archery, stuns with horses, interactive activities, or various contests.

The former football club FC Cetatea Suceava was named in honour of the castle. The club was active from 2004 until 2010 and played on the local Areni stadium.
