It is part of the Angkor temple complex, one of the smaller sites that is far less known by the casual tourist.
Anyone planning on visiting Siem Reap and going to experience the treasures of Angkor needs to know that Angkor Wat is just one of dozens of sites in the immediate vicinity - it is the biggest and undoubtedly the most impressive, but is also incredibly crowded and not particularly relaxing.
Many of the other temples - such as Ta Prom - are far smaller, but also far less busy - when we went to Ta Prom, we had it to ourselves for about an hour, and wondered around Indiana Jones style and were blown away by the serenity and beauty - highly recommended.
Unless you are flying in or out of Bangkok / Phnom Penh, due to Cambodia's primitive infrastructure getting to Siem Reap can be a nightmare.
If you are determined to travel overland, it's worth checking out the website below. The author is clearly an old Cambodia hand and his site is filled with regularly updated info, tricks and tips on how to get around.
And loads of other nice stuff on the rest of the site.
