The polygonal plan, with four angular bastions defines the typical irregular quadrilateral approaching the star-shape fortresses used in numerous other fortifications. The fact that the works lasted until (at least) 1670 is an indicator of the importance of this fortress and the care with which it was built. Unfortunately, its current state belies the grand project of the 16th century. The walls, which were initially high, were partially submerged by sand dunes (except to the sea).

Okhtyrka's fort was sitting on a shore of a small Okhtyrka river, where it makes a loop, forming a natural protection. The fortress was surrounded by numerous lakes, complicating approaches to it. The fortress had the shape of an irregular quadrilateral, and occupied a territory of the present city center, from the river to the area, where there is now "Intercession Cathedral" (outside the castle). It was surrounded by a wooden fence with five stone and fifteen wooden towers and two bastions.

The building consists of a large irregular quadrilateral, about . The south side, which houses the mihrab, is slightly longer than the north side. Seen from the exterior, the mosque looks like a fortress because of its massive walls without openings except in the facade, the extensive use of stone and especially the presence on the facade of the two truncated square towers at the northeast and northwest corners. Since the mosque does not seem to have ever included a minaret, it is likely that the call to prayer was from one of the towers.

The simple plan of an irregular quadrilateral without a keep had four round towers, a semicircular tower and two square towers, one of which formed the main entrance. The curtain walls were pierced with cruciform arrow slits. A year after completion of the castle, Gaston VII built a bastide close by and this, as well as the fortified church of Bellocq, became integral parts of the complex. In 1370, Gaston Fébus reinforced the castle and built new strong points in order to preserve his territory's independence from the powerful kingdoms of France, England and Navarre.

In 1538 the Senate approved his drawings of the new, much stronger Revelin Fortress. It took 11 years to build it, and during that time all other construction work in the city had stopped in order to finish this fortress as soon as possible. The new Revelin became the strongest of the city fortresses, safeguarding the eastern land approach to the city. Shaped in the form of an irregular quadrilateral with one of its sides descending towards the sea, it is protected by a deep ditch on the other.

The Cubist sculpture is a simplified, abstracted bust of a human head, inspired by primitive art and archaeological specimens: parallels have been drawn with the features of human figurines in Cycladic art. The head is flattened into an irregular quadrilateral plaque with slightly curving sides, which rests on an integral pedestal and base. The plate has two shallow elliptical depressions, a deeper vertical along the left edge and a shallower horizontal one inside the top edge, interpreted as the nose and an eye. Copies of the sculpture were made in terracotta, plaster, marble, and bronze.

Castle of Mequinenza stands almost on the edge of a great steep right at the confluence of the Ebro, Segre and Cinca rivers in Mequinenza. Its plant is an irregular quadrilateral, with seven rectangular towers except one, the most robust, which is pentagonal. Few fortresses will have a better location than this one, contemplating an extensive and impressive landscape over the confluence of the rivers and their surrounding lands, reaching the Pyrenees on clear days. The building is an authentic Castle-Palace, one of the best that Gothic art bequeathed to the Crown of Aragon, dated to the fourteenth and fifteenth centuries.

The old Belgrade Town hall building was erected as a two- storey structure designed according to the mixed stylistic elements of classicism and romanticism. It had the base of irregular quadrilateral shape, conditioned by the shape of the plot. It was built in the regulation line which later on conditioned the regulation of the street as well as two side approaches. It had one tavern and the inn, 12 equipped rooms for passengers, 4 rooms and 1 guest hall, a kitchen, a laundry room, a stable for 30 horses, a wine cellar, a basement for the firewood and the shed for the carriage.

The exterior masonry of the structure adopts the usual technique of that period in Constantinople, which uses bricks sunk in thick beds of mortar. The walls are reinforced by chains made of small stone blocks. The building, the central plan of which was consciously repeated in the basilica of San Vitale in Ravenna and served as a model for the famous Ottoman architect Mimar Sinan in the construction of the Rüstem Pasha Mosque, has the shape of an octagon inscribed in an irregular quadrilateral. It is surmounted by a beautiful umbrella dome in sixteen compartments with eight flat sections alternating with eight concave ones, standing on eight polygonal pillars.

The heavily restored castle The building rises almost to the edge of a great precipice, being a closed mass of quite height, its plant is an irregular quadrilateral, with seven rectangular turrets except one, the more robust, that is curiously of pentagonal plant. Two towers flank the small door that is semicircular, under shield and protected by a bollard. Few forts will have a better location than this, contemplating a vast and impressive landscape, almost geological, on the confluence of the Ebro, Segre and Cinca rivers and their surrounding lands. It is not surprising that the Moncada, masters of the barony of Mequinenza chose this nest of eagles for their fortified mansion.

Also known as the "Grand Mechouar", this vast irregular quadrilateral space of 4 hectares occupied the northwestern corner of Fes el Jdid in an angle between the walls of the palace grounds to the south and the Moulay Abdallah district to the east. The military square was laid out in the mid-19th century by Abd al-Rahman de Saulty, a Muslim convert and officer in the military engineers corps under Sultan Moulay Abd al-Rahman (ruled 1822-1859). The creation of the mechouar required a minor diversion of the Oued Fes river at the time. Bab Bou Jat, the main western gate of the Moulday Abdallah quarter, once opened through here but was closed off in the 20th century.

Along the southwest battlement is the two-storey tower with 12 arrowslits, posterior capped by a vaulted ceiling Part of the staircase leading to the northwest battlements The castle is found in an isolated urban context, on an elevated zone known as the Costa da Vila Fria, with many of the towers and walls extending over the landscape. The plan of the castle is an irregular quadrilateral polygon, defined by four walls, flanked by towers in the south, west and north. The Porta da Vila (Town Gate), in the southwest, is surmounted by a capstone with the coat-of-arms of King John II of Portugal, and opened to the courtyard where there are several older buildings. To the south is a cistern, alongside the northeast part of the fortification's wall, with spaces for the alcalde located in a two-storey structure.

In the rectangular floor plan of the original mosque there were three aisles and rows of arches to the west, east, and south of the courtyard, while on the north side was a single aisle forming a gallery. The Wattasid-era expansion, however, added an irregular quadrilateral extension to the west, with an oblique outer wall, making the overall floor plan today asymmetrical. On the southern (qibla) wall of the prayer hall, the mihrab (niche symbolizing the direction of prayer) is aligned with the central axis of the courtyard. The original entrance of the mosque was likely located on this same axis, on the opposite northern side of the mosque; however, the Marinid-era minaret appears to have been built on this location, blocking the original entrance, and other entrances were opened up instead to the west and east.
