In the 15th century, the Olivetan Monks built the Monastery of Nosta Signoria delle Grazie along the Gulf of La Spezia nestled between the Castellana and Muzzerone Hills. Inside are paintings and frescos, some of which date back to 15th century. It became a parish church in the early 19th century. On September 8 of each year, it hosts a festival that attracts thousands of visitors.
