As well as offering a comprehensive overview of the history of Thailand, the National Museum is of interest to school trip groups as an important historic building in its own right. It was originally a palace built for the king's brother, who held the title of second or 'deputy' king, and was called the Wang Na or Palace of the Front - so named for its strategic position between the Grand Palace and the northern boundary of the city. The museum is laid out in such a way that the original rooms and gardens of the palace can still be seen, as well as the residential temple. After the title of second king was abolished, the pala ce became a museum. A notable part of the museum's collection is the Red House, a former queen's residence, a graceful wooden house built without any nails, which could be easily dismantled and reassembled.
