Outside the town (in Maardu village), south of the road to Narva lies Maardu manor, one of the oldest preserved baroque manor houses in Estonia. It traces its origins to 1389, but the current building dates from the 1660s with additions made in the 19th century. The landlord of the manor Herman Jensen Bohn in 1739 funded the printing of the first bible printed in Estonian.
Maardu may be divided into four parts:
Kallavere (the centre of the city where most of the public institutions are located)
Muuga aedlinn (former garden city, now a light residential suburb more connected to Tallinn than Kallavere)
