Boudhanath (also called Boudha, Bouddhanath, or Baudhanath) is one of the holiest Buddhist sites in Nepal, it is said to entomb the remains of Kassapa Buddha. The ancient Stupa is one of the largest in the world. There were three sources about the builders of this holy stupa: (1) Nepalese Licchavi king Śivadeva (590-604 AD), (2) Nepalese king Mānadeva (464-505 AD), and (3) Tibetan emperor Trisong Detsän (755 to 797 AD).

Swayambhunath (Swoyambhunath, a.k.a. Monkey Temple) is an ancient religious complex atop a hill in the Kathmandu Valley. Legend said that this stupa was founded by the great-grandfather of King Mānadeva (464-505), King Vṛsadeva, about the beginning of the 5th century. Much of Swayambhunath's iconography comes from the Vajrayana tradition of Newar Buddhism. However, the complex is also an important site for Buddhists of many schools, and is also revered by Hindus. The complex consists of a stupa, a variety of shrines and temples, some dating back to the Licchavi period.

Kapilavastu is the ancient Shakya kingdom where Gautama Buddha grew up, including his family home and garden.

During the late Anuradhapura period, the royal family and nobility of Sri Lanka strongly supported Buddhism. As such, they frequently commissioned works of art and donated these items to Buddhist temples. (see Mihintale)

According to Dipavamsa and Mahavamsa, Thera Mahinda, son of Emperor Ashoka, came to Sri Lanka from India on the full moon day of the month of Poson (June) and met King Devanampiyatissa and the people, and preached the doctrine. The traditional spot where this meeting took place is revered by the Buddhists of Sri Lanka. Therefore in the month of Poson, Buddhists make their pilgrimage to Anuradhapura and Mihintale. Thus Mihintale is called the cradle of Buddhism in Sri Lanka.

Sri Dalada Maligawa (the Temple of the Sacred Tooth Relic) is located in the royal palace complex which houses the relic of the tooth of Buddha.

Adam's Peak (butterfly mountain) is well known for the Sri Pada (sacred footprint), a 1.8 m (5 ft 11 in) rock formation near the summit, which in Buddhist tradition is held to be the footprint of the Buddha.
