Structure 1 is the tallest building at El Puente, measuring tall. It appears to have been built in the 7th century AD, its earliest version bears a stylistic similarity to buildings from that period in Copán. It was a radial pyramid with six tiers and stairways on all four sides, with the east and west stairways being the best preserved. It was topped by a superstructure with three rooms and fallen remains indicated that it had a vaulted roof with channels to drain off rainwater. The wall was decorated with sculptures of three human figures. Archaeologists have tunnelled within the structure and have also excavated around it, revealing a large amount of ceramic fragments, burnt clay, and burnt maize and beans. The structure has been badly damaged by looters.
