Isola di Felettino is mentioned in various documents dating back to between 950 and the 13th century. It is possible that the place name Felettino derives from the name "felce" (meaning fern), or from the word "file", meaning company, in reference to the group of Byzantine soldiers who were posted on the island. The church of San Vittore and San Michele dates back to before the year 1000, and was originally positioned inside the castle of Isola, which has now completely disappeared. Isola was also once home to a hospice for pilgrims dedicated to San Giacomo Apostolo.
The village still retains its medieval appearance, with paved streets, archways and galleries, as well as the oratorio of San Bernardo, even if the latter owes its current appearance to restoration works completed in the 18th century.
The parish church is now dedicated to Sant’Anna, who was worshipped as far back as the 16th century. The church was opened in 1986. The design of the structure uses simple, clean lines, giving the structure a very modern appearance. The interior consists of one aisle, and is decorated with paintings and wall hangings created by spezian artist Rino Mordaci. The church also houses a statue of Sant’Anna that was recovered from the church of San Bernardo and whose creator remains anonymous. The town of Isola is centred around the church of San Giacomo Apostolo, located on the hills facing Spezia, which give onto an excellent panoramic view of the region. The church houses valuable contemporary paintings, a precious altar and the remains of San Giustino, dating back to the 18th century.
