Building complex and canal, glossed 42

The gloss in this instance is referring to the canal, which according to the glossary was named (probably by the Spaniards) for Jesus. We can also tell that the canal was navigable based on the canoe in the image. The building complex is interesting in that it is the last major structure in the south east corner of the Spanish traza before open land, yet we do not know what the structures were used for.
