Western Metal Supply Co. Building (integrated into Petco Park)

The Western Metal Supply Co. building is a 1909 brick industrial building that was preserved and incorporated into the southwest corner of Petco Park when the ballpark was developed. Its original brick façade remains visible from within the stadium, making it a distinctive historic element of the ballpark's design. The preservation of the building is often cited as a notable example of integrating a historic structure into a large modern sports facility.
