The oldest Caitya in Nepal is the Dharmadeva (Dhando) Caitya in Chabahil, Kathmandu. Other significant Caityas include Svayambhu Caitya, Boudha Caitya, and several Ashokan Caityas of Patan, among others.
Determining the origins of Caityas is challenging due to damaged historical records and limited local awareness about their importance.
Caityas represent the Triratna (Triple Gems): Buddha, Dharma, and Saṃgha, and also symbolize Adi Buddha, Dharmadhātu, Vajradhātu, and the Pancha Buddha.
