Rupea Citadel is 65 km from Brașov, built on a basalt massive, in the Cohalm Hill–Basalts of Rupea geological reserve.
It is a peasant citadel with four areas reinforced with polygonal towers.
The citadel is modified in time, by adding two interior courtyards and three defense towers.
The citadel is built on four premises: Upper citadel (Romanian: Cetatea de sus, premise I), Middle citadel (Romanian: Cetatea de mijloc, premises II and III) and Lower citadel (Romanian: Cetatea de jos, premise IV).

Each is identified by a special brickwork belt, corresponding to different eras, marked by the evolution of weapons, siege techniques or level of development of the settlement and the seat on which depended the financing of work.
In turn, the towers have an identity covered by an own name that, in part, betrays a certain feature (often related to the function) resulted from their historical development.
These elements worn various sizes and architectural features: the oldest had battlements in rectangular zigzags (which have not been reserved), and the most recent had semicircular merlons, more decorative.
Their embrasures took the form of simple slots, and the openings for firearms were made with angles of fire as large as possible or special, to the base of walls, fit in prominent niches, with arrangements of stepped pyramids.
Behind the walls, traces of brickwork betray the foundations of watch roads, sometimes on two levels.

The first premise of the fortification system is the Upper citadel which dates from the prefeudal period, 10th–13th centuries.
It comprises the latest expansions, including the Bacon's Tower (Romanian: Turnul Slăninii), specific to Saxon communities.
Also here can be found the 59 m-deep fountain, the only source of water certainly identified in the citadel.
The fountain was built in 1623, after a work of several months, during the princeship of Gabriel Bethlen.
The upper citadel has an area of over 1,500 m².
The entrance to the upper citadel was a narrow corridor, the gate under the Gunpowder Works' Tower (Romanian: Turnul Pulberăriei).
To the inside can be observed traces of rooms that served as homes for the refugee population in the citadel during sieges.
The best-known rooms in the upper citadel are the Count's room (Romanian: Camera judelui) and the Priest's room (Romanian: Camera preotului).
But these are very difficult to identify nowadays.

The Middle citadel was built in the 15th century and was enlarged in the 18th century.
Here can be identified the Tower with Bars (Romanian: Turnul cu Gratii), the Chapel (Romanian: Capela) and another pentagonal tower, unique in Europe, gateway to the middle citadel.
The chapel is a large building (the last known restoration in 1718), with multiple roles, inside which must be arranged a Lutheran chapel, soberly decorated, after cult demands.

The Lower citadel was built as from the 18th century.
From this period dates the house of citadel's watchman (1850) and the military warehouse, built in the early 19th century.

Rupea Citadel has the form of an ascending spiral (snail shell).
