Editing Dionysius I of Syracuse (section)

==Walls of Syracuse==
In 402 BC Dionysius I began building the walls of Syracuse, which included an impressive citadel, the [[Euryalus fortress]], protecting the plateau to the northwest of Syracuse, the remains of which are still visible today. The walls were completed in 397 BC and had the following characteristics:

* Length: 27 km
* Width at base: 3.3 m to 5.35 m
* Number of known towers on circuit: 14 (including Euryalos)
* Largest tower: 8.5 m x 8.5 m
* Deepest ditch (at Euryalos fortress): 9 m
Building so big a fortress would have involved installing well over 300 tons of stone every day for 5 years.<ref>{{cite book |title=The Seventy Wonders of the Ancient World |url=https://archive.org/details/seventywondersof00scar |url-access=limited |editor=Chris Scarre |year=1999 |publisher=Thames and Hudson |pages=[https://archive.org/details/seventywondersof00scar/page/210 210]–211|isbn=978-0-500-05096-5 }}</ref>
