Palazzo Pavone

Honorary Professor Prayad Pongdam, the late Thai National Artist in printmaking, created this space nearly three years ago as his art gallery and workshop with an attached resort. Sadly, he passed away only six months after the opening, leaving the space to operate as a museum for some 150 cherished art pieces. Mediums vary from prints and oil paintings to sculptures and carvings. They also have a cafe and shop selling souvenirs of his iconic printmaking pieces. The resort offers four room types: standard (B3,200), deluxe (B3,900), family room (B4900/4 pax) and pool villa (B6,000).
