The Royal Thai Navy's conference hall, officially known as the Thai Naval Auditorium, was specially built to receive world leaders during the 2003 APEC summit in Bangkok.

It is said to be made of reinforced materials and with bulletproof windows. For security reasons it was built within the compound of the Royal Thai Navy, making it inaccessible to outsiders.

The bridge in the photos was also built prior to the meeting to allow the guests and staff access to other buildings within the compound.
