On the northwest coast rests Qatar's greatest archaeological page: Al Zubarah (UNESCO 2013) — a pearling and trading town that flourished in the 18th century, was abandoned, and lay preserved under sand with walls and houses, guarded by the restored 1938 fort as site museum. Fort and displays open the understanding, then the town ruins for the devoted; an hour from Doha — join a northern day with nearby Jumail's sea-side ruins; winter strictly, the site shadeless.
