The old masjids in Qatar only have two "saf"s with a rear courtyard like the ones in Simaisma, Wakra & Zikreet. They are still utilized for congregational prayers five times a day.
Sadly, the one in Dhakira could use some repairs.
There are also 50-year old ruins of masjids and abandoned fisherman villages in Al Arish & Al Jemail worth visiting.
