The new city pillar shrine
The city pillar of Nakhon Phanom is a very modern shrine. It was only put up in 1992. City Pillars are more of a central Thai tradition than a northeastern one. The pillar itself is a god-covered shaft sunk into the ground near the old city hall. The pavilion covering the pillar does have local touches, such as a spire that looks like the Phrathat Nakhon.
One of the guard towers of the old city prison
Slightly more interesting is the nearby park that was once the city's jail. The corner guard towers have been left in place, but most of the rest of the prison is now landscaped park. There's a clinic near the road and a small museum as well.
