These are the remaining keeper images in my files for El Puente, which was very much worth the visit.
Near the river was a residential complex, or perhaps a bathing complex, I'm not sure. It was quite near what could have been a ball field. The soil near the river was very marshy and unstable, and I was amazed at how well these buildings remained for so long. Later, I took images of my wife atop a temple, and a friend below.
The age of the El Puente makes it contemporary with Copan, with most architecture dating to about 800 AD. This may have been a vassal state that paid tribute to Copan. The foundations of these temples were generally remarkable, although there seemed to be a slight settling problem. Some ruins appeared to be sinking in the middle into the soft soil near the river.
Probably the reason why this Mayan ruin is so rarely visited is because no buses go there directly, and because the drive off the main highway is more than the 10 kilometers reported in the Lonely Planet Guidebook. There's a clear sign for the turn-off though just after La Entrada, on the road to Copan from San Pedro Sula. Plus, the road is paved all the way, which is very unusual for a road going nowhere in Honduras. It's a pleasant country road.
