This is a beautiful photo showing Jalan Kauman towards Solo/Boyolali from Jalan Diponegoro. The two buildings still exist as high schools, however they are blocked by newer constructions.
Overlooking mount Merbabu on a clear day, this is one of the most telling photo of Salatiga I have ever seen. It speaks a lot about the geography and character of the town - quiet, beautiful, and humble.
Thanks to Dede for sharing this in Facebook.
Date unknown. I would guess the 1960's
