The parks and gardens in Bratislava have formed a part of the landscape of the capital of Slovakia since the Middle Ages. Some of the historical gardens of Bratislava had such architectonic value that they were widely known outside of the city and well beyond the borders of the Kingdom of Hungary. Perhaps the best known garden in the city's history was the renaissance Pálffy Garden, with its famous landmark, a centuries-old linden tree encased in a wooden terrace frame, seven floors in height.
