The main temple was dedicated to Ramesses II and to the four universal gods Ptah, Re-Harakhte, Amun-Re, and to Ramesses II himself. Of the seven temples he built, Abu Simbel is considered to be the most impressive. Ramesses II, called "the Great," built seven rock-cut temples in Nubia.

This temple was not seen by Europeans until J.J. Burckhardt discovered them in 1813. The temple, called Hwt Ramesses Meryamun, the "Temple of Ramesses, beloved of Amun," was begun fairly early in Ramesses’ long reign, commissioned some time after his fifth regnal The facade of the main temple is 108 feet high and 125 feet wide with four colossal seated statues about 65 feet high wearing the double crown and having the cartouches of Ramesses II.

At the feet of the calossus, beginning on the left are Queen Nofretari, Prince Amenhirkhopshef, the Kings mother Muttuya, Princess Bent'anta, unnamed, but probably Esenofre, Princess Nebettawy, Queen Muttuya, Princess Nofretari, Princess Merytamun, Princess Beketmut, Prince Ri'amsese, and Queen Nofretari, who where all members of Ramesses II's family.

Above the doorway in a niche stands the sun god, a falcon headed representation of Ramesses, holding a war-scepter which shows the head and neck of an animal which is read as user, in his right and a figure of Ma'at in his left. This cleverly creates the Kings throne name of User-Ma'at-Re. At the top of the facade is a row of baboons which are thought to be greeting the morning sun and indeed the monument looks best at that time. The sides of the thrones next to the entrance are decorated with Nile gods symbolically uniting Egypt, while below are prisoners, representing conquered nations, to the left, African and to the right, Asian.

The entrance leads into a Grand Hall which is 57 feet high and 52 feet wide and was cut from the rock. It is supported with eight pillars with statues of Ramesses. The statues on the north side of the hall wear the double crown, while those on the south the white crown of upper Egypt.

Just as other temples in Egypt, the floor and ceiling taper off to draw focus to the sanctuaries in the back of the temple. The reliefs on the north wall of the Grand Hall show scenes from the Battle of Kadesh. Other walls depict the king slaughtering captives in front of the gods Amun-Re and Re-Harakhte, and storming a fortress with his three sons.

To either side of the Grand Hall are smaller rooms, two to the South and four to the North. Most suggest that these rooms were for storage (treasure rooms) but elsewhere it is suggested that they were used for festivals related to the Kings Jubilee.

Beyond the Grand Hall is the second hypostyle hall with its flowered pillars. Scenes in this hall show the King and his wife, Nefertari making offerings to Amun and Re-Harakhte (the Sun God), and beyond that is the three chapels, the central one containing the four deities worshipped in the temple (including Ramesses II).

A Solstices occurs twice a year on or about February 20-22nd and October 20-22nd when the rays from the sun enter the front of the temple and bathe the statues of the Gods 200 feet inside the temple with light. Interestingly enough, all but Ptah, the source of Chthonian life. On either side of the Facade are two small chapels. At the Southeast corner of the facade there are three stelae. One of these is called the Marriage Stela and documents the marriage of Ramesses II to the daughter of the King of the Hittites. On the other side of the Facade is the Sun Chapel, an open court dedicated to the sun. Here, there are pillars with cavetto cornices. The one with steps held four praying baboons, the other a chapel with images of Khepri and Baboon-Thoth. The latter is now in the Antiquities Museum in Cairo.
