St. John's Lutheran, a lovely old marble church on Emory Place, stands to the left of an interesting irregular open space between Victorian buildings. in the 1880s and 90s it supported an ultimately unsuccessful market square, with a a crookedly shaped market house known as the Central Market. Look for Harb's Carpet and Oriental Rugs, an 80-year-old business opened by enterprising Arab immigrants in the 1920s and still run by the same family.
Give your regards to Broadway. For this detour, from Summit Hill turn left onto Henley, which quickly becomes Broadway.
