Hor Kaew Mukdahan

This eye-catching 65m-tall tower was built for the 50th anniversary of King Rama IX's ascension to the throne. The nine-sided base has a good museum with displays (labeled in English) on the eight ethnic groups of the province. There are great views and a few more historical displays in "The 360° of Pleasure in Mukdahan by the Mekong" room, up at the 50m level. The ball on the top holds a locally revered Buddha image believed to be made of solid silver.
