The Temple of Apollo in Corinth.
The image below is from the Acrocorinth above the city and shows Cenchreae and Lechaion, the 2 ports on either side of the Corinthian isthmus. When Paul visited the Acrocorinth it was the location of the temple of Aphrodite. The temple has been destroyed and ruins of a castle remains. 
The modern canal connecting Cenchreae and Lechaion, the 2 Corinthian ports. In Biblical times boats would be unloaded and carried overland the 4 miles. The canal is as straight as an arrow.
