The first version of the San Procolo Church in Verona was built around the 5th century, in the center of a necropolis. The present church dates back to the 12th century, when it had to be completely rebuilt after an earthquake. The highlight of the church is the crypt, which contains ruins of said necropolis.

History
The Church of San Procolo is dedicated to the Fourth Bishop of Verona. The remains of this saint from the 4th century are buried in the church.
The original church was built in the 5th or 6th century. At that time it stood in the middle of a large Roman and Christian necropolis.
The church was reconstructed in the 12th century. This was necessary after the earthquake of 1117 had caused severe damage.
A complete restoration took place in the 16th century.
A later restoration in the 20th century uncovered several archaeological ruins.
Description
The facade is characterized by 2 biforas and a hanging protiro. The arch of this protiro is decorated with 14th century frescoes. The large octagonal window dates from the 18th century.
The San Procolo Church has a single nave. The interior is decorated by works of art by Antonio Badile and Giambettino Cignaroli.
A central staircase leads to the crypt of the church. This was built in the first half of the 11th century. Halfway up the stairs one can see some ruins of the early Christian church. There are also finds from the necropolis. These include 16 tombs, a Roman sarcophagus, friezes and an inscription (also from Roman times). The oldest tomb dates back to the 1st century AD. One of the tombs was found in perfect condition, with the bones of three skeletons inside.
The crypt consists of three naves. These are supported by six columns and twelve pillars along the sides. The capitals originate from different eras. The oldest are reused Corinthian capitals dating back the 8th century. The rest dates from the 10th and 11th centuries and is decorated with geometric and plant and animal motifs.
Restorations carried out in the last century brought to light frescoes painted between the 12th and 14th centuries.
