I found a lovely UNESCO site in Thailand in December. It was not only a long time ago that I have received a card from this country, its also my first UNESCO card. It has traveled a distance of 9231 km in 31 days. It shows us Wat Mahathat in Ayutthaya.
Founded c. 1350, Ayutthaya became the second Siamese capital after Sukhothai. It was destroyed by the Burmese in the 18th century. Its remains, characterized by the prang (reliquary towers) and gigantic monasteries, give an idea of its past splendour. (source: UNESCO.org)
