"Most of the qasabas have a circular plan, although some are square. Sometimes they have a band of quartz stones just below the windows or framing the windows – one well preserved example is at the top of Wadi Ain. The remains of a martello tower-like stone structure are just off the dirt track north of Al-Masnah. It appears to be an interesting antecedent of the Asir farmhouse and perhaps closely related to the qasaba. It is in ruins now, but was once a dwelling and is strongly defensive." One account says about a traditional village in Al-Bahah, Saudi Arabia: "Even the road that leads to the village is impressive, and several historical stone and slate towers dot the way. Al-Bahah Province is known as the region of 1001 towers, once built to protect villages, roads and plantations from rivalling tribes. Today, these towers are abandoned, and many of them are partially or completely in ruins."
