Logia Adelphia

The Logia Adelphia is a historic building located in Mayagüez, Puerto Rico. It was built in 1912, and was designed by Sabas Honore, a prominent local architect. It was listed on the U.S. National Register of Historic Places, for its architecture, in 1986. The north facade, facing on the street, is elaborate and preserved. The interior has been renovated, and no longer reflects its original design.

In 1984, the building was still being used by Adelphia Lodge #1, the oldest Masonic Lodge located in Mayagüez.
