Gwalior Fort dominates the city and is its most magnificent monument. It has been a scene of momentous events  imprisonment's, battles and jauhars. A steep road winds upwards to the Fort, flanked by statues of Jain tirthankaras, carved into the rock face. The magnificent outer walls of the Fort still stand, two miles in length and 35 feet high, bearing witness to its reputation for being one of the most invincible forts of India. This imposing structure inspired Emperor Babar to describe it "the pearl amongst the fortresses of Hind." Within the fort are some marvels of medieval architecture. The 15th century Gujari Mahal is a monument to the love of Raja Mansingh Tomar for his Gujar queen, Mrignayani. After he had wooed and won her, so the story goes, Mrignayani demanded that he build her a separate palace with a constant water supply from the River Rai, via an aqueduct. The outer structure of the Gujari Mahal has survived in an almost total state of preservation; the interior has been converted into an  Archaeological Museum.

Also built by Raja Mansingh is the Man Mandir Palace, built between 1486 and 1517. The tiles that once adorned its exterior have not survived, but at the entrance, traces of these still remain. There is a charming frieze here of ducks paddling in turquoise waters. Within, the palace rooms stand bare, stripped of their former glory, mute testimony to  the passing of the centuries. Vast chambers with fine stone screens were once the music halls, and behind these screens, the royal ladies would learn music from the great masters of the day. Below, circular dungeons once housed the state prisoners of the Mughals. The Emperor Aurangzeb had his brother, Murad, imprisoned, and later executed, here. Close by is Jauhar Pond, where in the Rajput tradition, the 'ranis' committed mass 'sati' after their consorts had been defeated in battle. Though the major portions of the Fort were built in the 15th century, references to this gigantic complex can be traced back to 425 AD. Older than the city is the Suraj Kund within the Fort walls, the original pond where Suraj Sen, or Suraj Pal as he was later known, was cured by the Saint Gwalipa.
