The castle was built in the Classicist style, and an old driveway stretches behind the building. Its symmetrical and rather puritan main facade is defined by the tympanum supported by four simple pillars. Its only decorative element is the striated cornice. The building’s doors and windows have simple, undecorated lintels; the two planes of the roofing are reminiscent of the Baroque style.
Initially, the free-standing, single-storey building has had an U-shape ground plan. In front of the main entrance, located on the middle risalit of the main facade, there is an open portico supported on wooden columns, which can be accessed by stairs. The triangular frontispiece of the terrace contains the coat of arms of the family, held by two lions.
The new fortification’s purpose was to take the nearby Bálványos medieval fortress' role which the treasury abandoned. The first mention of the fortress of Gherla dates back to 1539. The designer and builder of the castle most likely was the Italian architect Domenico da Bologna, who was at Gherla in 1540.
The building with a rectangular ground plan and high ground-level has a jerkin-head gable roof On the right side, the main facade is defined by the avant-corps, which originally had two heightened windows, but one of these windows was transformed into a door. The left side's corner is imitating a tower. The main entrance, located in the middle, can be accessed by a few steps.
