Wikimapia shows this building as a night market ("Hua Raw Night Market") in Ayutthaya.
I went at night (7pm) last month, and it was not open.
However, an esplanade 200 meters away was a very busy outside night market, with ~50 stalls. Coordinates: 14.365882, 100.574783
Is it the new location of the night market?
Or was it a special occasion, and Hua Raw still functions as a night market?
Or are they both active night markets, and one just happened to be closed temporarily?
