The card shows a sunrise reflecting off a Temple at Naksan.
It's a really lovely card...dont know why but this kind of cards with doors/windows seem to be very interesting...and also from what ive noticed, popular among postcard-collectors.
As for the Naksan Temple... it is a Korean Buddhist temple complex in the Jogye order of Korean Buddhism that stands on the slopes of Naksan Mountain and is one of the few temples in Korea to overlook the Sea of Japan (East Sea).
Naksansa was founded in 671, by the Buddhist monk, Uisang Daesa (Grand Master Uisang), an ambassador of the 30th King Munmu of the Silla Period (BC 57-AD 935) after he had returned from studying abroad during the Chinese Tang Dynasty, who, while meditating near the cave in which the Avalokitesvara Bodhisattva (Gwaneumbosal) was believed to have lived, was told by the Bodhisattva to build the temple there.
