The third courthouse to grace the public square, the handsome limestone classical revival structure was designed by Elmer Dunlap and built in 1916 at a cost of $171,000. It was separately listed on the National Register in 2001.
101-111 South Washington Street.
The center of the block houses the Assion-Ruffing City Hall built in 1864-1865 replacing the frame Northwestern Hall. "City Hall" refers to the grand hall on the third floor spanning all three bays and that was converted in 1881-1882 to the Lathrope & Ruffing Opera House. The building was separately listed on the National Register in 1998. On the alley in the 4-story Italianate built in 1865-1866 by John Brookbank. It was a hotel through much of its life as the Greenup, European, and Crosby Hotel. The top two floors were rented by John Lathrope to provide dressing rooms and sleeping accommodations for the Opera House. 101-103 S. Washington is the Ruffing block built in 1870 and replacing the frame Buford House. Edmunds Drug Store operated on the corner as did Margowski's in a later period. Clawson Appliance's occupies the south bay today as it has from the 1960s. 
105-109 S. Washington Street.
This detail highlights the limestone emtablature "City Hall" on the Assion-Ruffing building completed in 1865. Never a government building, "City Hall" refers to the grand hall on the third floor spanning all three bays. Decorative wooden corbels support the cornice. The center window is the "signature window" used in the logo design of the Dlephi Preservation Society. 
113-121 S. Washington Street.
On the alley at 113 S. Washington Street is an 1890s brick replacing the part of the Bolles block that burned. It houses Bill's Rock Shop today, but is remembered as Goff's 5 and 10. The two-bay brick block to its right was built in 1851 and is the oldest surviving brick on the square. It was the Bolles General Store and William Bradshaw's Jewelry and insurance business when built. The Ben Franklin Store was here for many years and currently houses the Delphi Antique Mall. The four-story 3-bay Italianate structure is the Spears & Case building erected in 1855. James Spears, canal merchant, and Reed Case, engineer for the canal, owned and operated slaugherhouse, grain warehouse, and other enterprises. The Spears & Case Bank anchored the corner. The facade of the building was modified in 1865 to match the newly built C & G Moore block diagonally across the intersection. The parging coat of concrete was added by 1906 to resemble cut stone.
