Admire some superb modern engineering at Longmen Bridge. A combination of function and aesthetic, it's one of this region's most significant structures.
You're spoiled for sightseeing choice when visiting Luoyang. Longmen Bridge is a good place to kick off here, but there are lots of other worthwhile sights to experience. China National Flower Garden and Lingtai Ruins are not far from the modern structure and will round out your day nicely.
