A tourguide will give an introductory information of Thailand's first brewery, starting in 1929 when Praya Bhirom Bhakdi first thought of a new business venture. The timeline runs through War Time Siam when the brewery had to find alternate products to sell, to keep the company afloat, and finally to 1967 when this building that now houses the Singha Museum was built as Brewhouse No. 2, in extension of the original Brewhouse No. 1 next door.
