In my post below, I wrongly stated that the Ghana temple was the first one to have murals. My bad. Los Angles (1956) was the last temple to have murals before the recent spat of temple building. The Winter Quarters Temple didn’t have murals, but it has very large, framed paintings in the ordinance rooms. This paved the way for the Columbia River Temple, which was the first recent temple to have true murals. Since then, murals have been included in the temples listed in this comment. In addition, there have been murals in the Monteray, Mexico temple, and the Nauvoo Temple (although these were commissioned after the temple was dedicated).
