The Grand Palace is a huge compound (218,000 sq meters) which houses the royal residence, throne halls, government offices, and the renowned Temple of the Emerald Buddha. This tour is a must-see when in Bangkok, especially if you appreciate architecture. The buildings, temples, and statues are magnificent. The gilded temples, the intricate designs and tiling are tantalizing to the eyes. The Emerald Buddha is a very sacred statue that is highly revered by Thai people. It is a small Buddha statue that is entirely carved out of jade. There are english-speaking tours given throughout the day.
When heading over to The Grand Palace, be careful of scam artists who will tell you that the palace is closed for a Buddhist holiday. Then they will try to steer you to a different location. When couple people fed me this line, I still went to the palace to see for myself if it was indeed closed and it was very much open, filled with hundreds of other visitors. A healthy dose of skepticism is a valuable tool when traveling.
