This fort is an example of purely “Masculine” architecture. It places function over form. This can be gauged from the fact that the fort originally had no permanent building for living.

Stone carvings

These carvings are found on the gate and in the mosque. Most of these are engravings in Arabic and sunflowers.

One of these carvings is inside the Shahi Mosque outside the Pesh Imam's (Prayer leaders) room. The carving is of the word "Allah" (God) in Arabic. The same carving is also done on merlons on top of Shahi Mosque.

The sunflower motif is on each sides of the arches of Shahi Mosque. It is also present in the guard post in between each gate.

Calligraphy

Most of these inscriptions are on the Shahi Mosque. On the outer wall of the mosque the “Kalima” is written in beautiful calligraphy on both sides of each arch of the Shahi Mosque. The Naskh script is used.

There is an inscription in Persian on the Shishi gate which gives the date of start of construction. The same inscription is also found over the Talaqi gate.

There are other inscriptions on the Khwas Khani, Langar Khani and Gatali gate.

Tilework

These tiles are found on Shishi gate. This type of tile became extremely popular with the Mughals who further refined them. The tiles on Shishi gate are the earliest example of the usage of these tiles. These tiles were made in Lahore.

Plasterwork

Plaster has been used in the Shahi Mosque.

Machicolations

Machicolations are small drains that lead from the inside to the walls outside. They are built into the walls and are used by the soldiers on the inside to pour molten lead or other hot liquids on soldiers trying to scale the walls. The Rohtas Fort has hundreds of them and each one is beautifully decorated with geometric patterns. The pictures is of a machicolation near the Langar Khana (Mess Hall).
