Nepal-Lumbini

Today, the wider Lumbini complex — a grand three miles (4.8 km) long — is part of a huge UNESCO World Heritage Site. It consists of dozens of monasteries built by several Buddhist countries (all in their national styles), the sacred Bodhi tree, an ancient bathing pond, the renowned Ashokan pillar, and the Mayadevi Temple.
