The Castle, built within the Middle Ages walls, was once the seat of the administrative and judiciary power of the county. It is divided into the Corte dei Lanzi (with foundings of a high tower demolished in the 16th century), the Palazzetto dei Conti (13th century) and the Palazzetto Veneto. The Lanzi were the armed guards, the term being an Italian form of Landsknecht. The palatine chapel, entitled to Saint Bartholomew houses canvases of the Venetian school of painting and traces of Renaissance frescoes. There is also a Museum of the Goritian Middle Ages.
The Cathedral (originally erected in the 14th century), like many of the city's buildings, was almost entirely destroyed during World War I. It has been rebuilt following the forms of the 1682 edifice, a Baroque church with splendid stucco decoration. A Gothic chapel of San Acatius is annexed to the nave.
The most important church of Gorizia is that of St. Ignatius, built by the Jesuits in 1680-1725. It has a single nave with precious sculptures at the altars of the side chapels. In the presbitery Christoph Tausch painted a Glory of St. Ignatius in 1721.
