Local art galleries are not really my thing, but the Tatham gallery was really well worth the effort. The gallery itself is in a historic building right in the middle of town. There are two small floors with a very varied selection of art. They have a focus on local artists and some of the works were stunning. A nice selection of village scenes, some great wood sculptures all mixed with more traditional western art.
If you are stopping over in PMB, it is definitely worth to take an hour and visit.
The gallery has a nice little coffee shop upstairs where you can sit on the balcony and watch the hustle of this provincial capital.
