Roerich did a series of paintings on Lahul, which included a painting on the Rohtang Pass, the Chandra River, Koksar and Gundhla. I have come across three different paintings of his on Gundhla. Maybe the Tower of Gundhla was the thing that excited him. In all three paintings on Gundhla the Tower figures prominently. I'm posting two of his paintings from Gundhla, a part of the Lahul series. As per his own writings Roerich was astounded on seeing the ancient castle of the Thakur of Gundla. The Gondhla Fort is the only existing Fort in Lahaul today and is under ASI protection now.
