Old Big Gun Museum


There is the Old Big Gun Museum right in front of the Defense Ministry of Bangkok building. It is possible to visit it any time and for free, because it is an open-air museum! It was once decided that the cannons should not be aimed at the Grand Palace. That is why they were turned the opposite direction.

This European-style building was constructed at an order of King Rama V in the second half of the 19th century. King Rama V’s long reign was a period of comprehensive reforms to make Thailand a modern state. The king studied western state system, established close ties with European powers. The ministry building is painted yellow with white lines, and the windows stand out with their green color – these colors were very popular in the past. There are 40 old cannons in front of the building facade, dating back from Ayutthaya period to Rattanakosin period. There are also French weapons exhibited here. Every part of the exhibition is accompanied with detailed historic overviews. The museum is often used as a film set.
