Once inside the fort, it felt different than others we had visited. More opulent.

You can read more of the forts history here. In a nutshell:

The aesthetic ambiance of the palace is seen within its walls on a four level layout plan (each with a courtyard) in a well turned out opulent palace complex built with red sandstone and marble consisting of the Diwan-e-Aam or the "Hall of Public Audience", the Diwan-e-Khas or the "Hall of Private Audience", the Sheesh Mahal (mirror palace) or Jai Mandir, and the Sukh Niwas where a cool climate is artificially created by winds that blow over the water cascade within the palace. Hence, the Amer Fort is also popularly known as the Amer Palace.^[4] The palace was lived in by the Rajput Maharajas and their families. At the entrance to the palace near the fort’s Ganesh Gate, there is also a temple dedicated to Sila Devi, a goddess of the Chaitanya cult which was given to Raja Man Singh when he had defeated the Raja of Jessore, Bengal in 1604. (Jessore is now in Bangladesh).^[3][8][9]

There are really two key areas. The central court yard and the third courtyard. It is beautiful.

Looking down from the walls you see the ruler’s herb garden. Cooled by the lake, it allowed the ruling family to grow foods that would not otherwise do well in this climate.

But the highlight of the fort is third courtyard which is breathtaking.

The building to the left of the entrance gate is called the Jai Mandir, which is exquisitely beautified with glass inlaid panels and multi-mirrored ceilings. The mirrors are of convex shape and designed with coloured foil and paint which would glitter bright under candle nights at the time it was in use. Also known as Sheesh Mahal (mirror palace), the mirror mosaics and coloured glasses were "glittering jewel box in flickering candle light".^[4] However, most of this work was allowed to deteriorate during the period 1970–80 but has since then been subjected to a process of restoration and renovation. Carved marble relief panels are placed on walls around the hall. The hall provides enchanting vistas of the Maota Lake.^[14]

A shot where wall and roof meet.

We wandered deeper into the fort.

An ancient ventilation shaft. Love the way the light comes through in the shot.

A beautiful fort, well worth the rather painful trip to get to the top.
