 Poblet Monastery, one of the largest in Spain, is considered similarly impressive for its austerity, majesty, and the fortified royal residence within.The fortified Maulbronn Abbey in Germany is considered "the most complete and best-preserved medieval monastic complex north of the Alps".The Transitional Gothic style of its church had a major influence in the spread of Gothic architecture over much of northern and central Europe, and the abbey's elaborate network of drains, irrigation canals and reservoirs has since been recognised as having "exceptional" cultural interest.
