Way older than the pyramids was Ggantija’s limestone ruins on Gozo, Malta. I had arrived at the site on my first visit only to discover that the ruins were closed on two days of the entire year, and I had arrived on one of them.
On my second visit, I was in luck. I hiked from Rabat to the ruins as I couldn’t count on public transport and skirted the complex of stone. At the entrance I passed through two huge slabs of limestone and peered at a structure believed to have been built around 3600 BC.
