Horyuji (Nara), Five-storied Pagoda
Not easy to tell based on the photo alone, but the caption says this is “The oldest wooden architecture in the world, constructed in the 600’s. About 32 meters high …” We are tempted to say it was 64 meters high when it was built, but the termites got half of it in the intervening 1400 years. But that’s not true, so we won’t say it. The card was mailed in (we think) 1985, with stamp and full postmark. Grade: 1
