Although there aren't any famous historical sites to speak of on the road itself, Khao San is a part of Rattanakosin and actually one of the oldest neighbourhoods of Bangkok. Around the street, there are a number of old shophouses and noteworthy temples. Aside from the interesting architecture, the area shows a mix of peoples and heritages that is typical for Bangkok. There are Buddhists, Chinese, Muslims, Mons, and of course a great number of foreigners in this small part of the city. All of this makes the area an interesting place for a glimpse of Thai life.
