Jordan's Khans & "Pavilions"

Jordan was once part of the vast Moghul empire when it stretched from the middle east to southeast asia. "King's Highway" in Jordan is known for its ancient palace & fortress ruins. Most have been reduced to rubble. But, some are remarkably preserved. Today I visited 2 of the "best preserved".
Top pic is of me in front of the Khrina. Because "the photographer" omitted some of it, I am including the middle pic which shows it all! Scholars have debated the Khrina's origin & purpose for centuries. One inscription on an interior wall was dated 710 AD - but scholars believe it was 500 years old when that inscription was made - estimating that is was built about 215 AD. Although it appears there are arrow slits in the walls - many scholars believe they were only for light & air circulation. Most believe it was a "khan" or inn. The interior 2 floors support this belief because they are each comprised of small rooms with a large interior courtyard. All are incredibly intact.
The bottom pic is of the Quseir Amra built in 740 AD as a "hunting pavilion" for the Moghul king. It is known for its well preserved interior frescos and "baths".
Both of the above are near one another in a barren desert < 130 miles from Iraq. Also saw a huge military facility where US & Jordanian troops train Iraqi "security forces".
