(CNN) — Made it your mission to visit every single UNESCO World Heritage Site on the planet?
That challenge is about to get tougher.
UNESCO’s huge list of World Heritage properties has grown even longer this month, with the global body voting to add 21 sites during the 41st annual World Heritage Committee session in Krakow, Poland.
That brings the total of UNESCO World Heritage Sites to 1,073.
Northwest England’s mountainous Lake District was among the new sites added to the list, the UK’s first national park to become a World Heritage property.
“The combined work of nature and human activity has produced a harmonious landscape in which the mountains are mirrored in the lakes,” says UNESCO’s statement announcing the inscription.
India’s walled city of Ahmedabad, founded by Sultan Ahmed Shah in the 15th century, was also added to the list, becoming the country’s first city to get a UNESCO nod.
Located on the eastern bank of the Sabarmati river, it “presents a rich architectural heritage from the sultanate period, notably the Bhadra citadel, the walls and gates of the Fort city and numerous mosques and tombs as well as important Hindu and Jain temples of later periods,” says UNESCO’s description of the city.
