The King Narai Fair is organized in February every year to commemorate the good deeds of King Narai the Great to Lop Buri and the nation. Lop Buri was the second city during that period where the king preferred to stay for nearly throughout the year with an exception for the rainy season when he stayed in Ayutthaya.
There are various activities in the fair such as light and sound presentation, ademonstration of Thai lifestyle, Wang Narai Night, Thai games by Thai kids (Chuk, Klae, Ko, Pia), local entertainment, and booths offering local products.
