The cornice and dormers are fine specimens of Victorian woodwork.

If you look up the word “Polithania” in your favorite search engine, you will find this building and nothing else. It was a bank and land office for Polish and Lithuanian immigrants (Poland and Lithuania have a long history of interconnection). Now it cleans teeth, but the original signs are still over the doors.
The Second Empire style is named after the Second French Empire of Napoleon III. Its most obvious characteristic is the mansard roof with dormers, which supposedly arose in France because, in buildings that were taxed by their interior space, attics were not taxed, and the space under the roof counted as an attic no matter how accommodating it was. The building here at the corner of Carson and 18th Streets is a splendid example of the Pittsburgh implementation of the style.
This church was built as the First Ruthenian Church (a Presbyterian church for Ruthenian immigrants), and later became a Byzantine Rite church. Now, like many other things on the South Side, it’s a bar.
Addendum: The architect was Chauncey W. Hodgdon, whose churches were usually in the Gothic style, but who adopted a mixture of classical and Byzantine for this very unusual congregation.1
Carson Street is the commercial spine of the South Side, but occasionally we run across a house left over from the time before Carson was almost exclusively commercial. Most of them have small offices on the ground floors now, but they retain their domestic external appearance. This house strikes Father Pitt as a halfway point between Second Empire and Italianate styles in local rowhouses; it’s notable for its prickly decorative ironwork on the roof.
