The Necropolis of Mesu 'e Montes complex consists of 18 domus de Janas (type of pre-Nuragic chamber tombs in Sardinia). The site dates from the Neolithic to Middle Bronze Age. Of particular note, tombs I and II with 12 chambers each, decorated with a variety of features, a ceiling reproducing a gabled roof and a circular hearth sculpted into the floor; and tombs III, IV and XVI, all of architectural interest, with a curved stele in the centre of the exedra.
Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split. The ruins of palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. Today the remains of the palace are part of the historic core of Split, which in 1979 was listed by UNESCO as a World Heritage Site.
While it is referred to as a 'palace' because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
The palace has a form of an irregular rectangle with numerous towers on the western, northern, and eastern facades.
