This impetus was followed by
his son and successor Oun Heuane "Happiness of the House". He is better known as
Sam Saen Thai, the builder of Vat Manorom, who led the way to the peak of Luang Prabang
Pothisarath gave new stimulus to the Theravada by abolishing the cult
of Phi at the beginning of the With Century, without succeeding however in eradicating it.
Saya Setthathirath, son of Pothisarath, marked the peak of Ian
Xang . To this day, Vat Xieng Thong bears witness to this great builder's achievements.
We should also emphasize King Vixounarath's contribution, Vat Vixun's builder; and that of
his successors who have also contributed to the religious art of this renowned city.
Thus, successive rulers of each period have provided the evidence
of an unique culture. Also worthy of mention are the outstanding ongoing efforts by the
State, the province, the people and international organizations, in making this city a
world heritage site.
