It stands at 739 m (2,425 ft) above sea level and is located immediately to the east of the capital, San Marino. It was inscribed as a UNESCO World Heritage Site in 2008 under the combined title "San Marino Historic Centre and Mount Titano". Inscribed under reference no. 1245 criteria iii, the two together encompass an area of 55 ha with a buffer zone of 167 ha. It encompasses the Mount Titano and the other structures such as the fortification towers, walls, gates and bastions, as well as a neo-classical basilica located on it and its slopes forming a small but unique urban conglomerate.
Straddled on the ridge of Mount Titano is the city of San Marino of the Republic of San Marino on the eastern part of the Italian peninsula, it has a hoary history starting from early 4th century. According to the legend related to the Mount and its precincts a small monastery existed on top of the Mount during the 8th century. The mountainous landscape provides excellent views of its surroundings, and its isolated location ensured the needed seclusion for San Marino to survive as a Republic over the past several centuries.
The Guaita fortress is the oldest of the three towers constructed on Monte Titano, and the most famous. It was built in the 11th century and served briefly as a prison. It is one of the three towers depicted on both the national flag and coat of arms. San Marino also has a cake known as La Torta Di Tre Monti (Cake of the Three Mountains/Towers), as a symbol for the area. It is something of a layered wafer cake covered in chocolate.
