Loggia dei Mercanti, Renaissance arcade in Piazza del Popolo, Ascoli Piceno, Italy.

The Loggia dei Mercanti is a Renaissance arcade in Ascoli Piceno featuring five arches supported by Corinthian columns with leaf-decorated capitals. The stone structure runs along the right side of the San Francesco church and connects different parts of the square.

The Wool Guild (Corporazione della Lana) commissioned the loggia as a display space for its goods. Work began under the Lombard master Bernardino di Pietro da Carona and was finished in 1514 by Francesco Rubei of Villagona. The design is of uncertain attribution, variously proposed as Cola dell'Amatrice, Benedetto da Maiano or Bramante. A brick crenellated cornice was added above the original travertine cornice at a later date.

The loggia was commissioned by the Corporazione della Lana, the Wool Guild, which used the covered space to display and sell its cloth. The name recalls the merchants who traded under its arches. The guild's patronage tied the building directly to one of Ascoli Piceno's wealthiest trades.

The structure sits at the intersection of ancient Roman roads and links Corso Mazzini with Piazza del Popolo in the center of Ascoli Piceno. The location is easily accessible on foot and lies amid the main squares and streets of the old town.

Inside the arcade is a travertine plaque from 1568 with measurement standards for bricks carved into the stone that served as reference norms for brick production. These marks show how precisely Renaissance craftsmen wanted to control their manufacturing.
