1. The purple dot will be the new Martiri Metro station. It is the top entrance (20 meters above via Chiaia. The two lines across v. Chiaia are a bridge to allow access from the north onto Mt. Echia. The dotted line leading from #1 to the SW shows the path of the new Metro train tunnel still being built.
2. The Grotto of Mithra.
3. & 4. are related. N. 4 is where the Bourbon Tunnel builders first dug into the hill. That space now houses a multi-story car-park; that opens onto n. 3, the old Carafa Quarry and the entrance to the Bourbon Tunnel archaeological site
5. West entrance, 700-m. "Vittoria" traffic tunnel (1929). It exits on the port road below the Royal Palace, just off the right-hand side of this map.
There were many changes to the city from 1885-1915. They include the new blocks shown below in orange along the sea as well as via Partenope. It is all on land-fill. The original seaside roads were via Chiatamone and via S. Lucia on the west and east, respectively. Via Chiaia bounded Mt. Echia on the north.
The irregular shapes shown in green and blue are cisterns cut into the rock at various times through the centuries. They were joined to various aqueduct lines (the black lines). No surface structures on Mt. Echia are shown; the green patches are blocks of buildings; the white spaces are streets and squares.
Numbers 2, 3, 4 & 5 are all at street level (almost sea level), well below #1 and the entire Echia hill. The hill slopes up from #1 to #7 (c. 100 m. above sea-level).
6. Piazza Plebiscito, with the Royal Palace on the east is well above the street and sea level of the western side of the Echia Hill. The dotted lines at #6 show the now abandoned tunnel of the Rapid Train line from the 1980s.
7. The original "corner" of Mt. Echia. The solid line indicates a large, high retaining wall.
8. The Lamont Young ramp. You can hike up to the Mt. Echia height here. Or you can
(a) come in at #1;
(b) walk up at the south side of Piazza Plebiscito;
(c) use another stairway just north of #7 on the map.
"The huge quarry in green [top left on map] has an interesting back story as well. The entrance to what is now the multi-screen cinemaplex, and what you will remember as the old Metropolitan Cinema is right there on the curve in via Chiaia not far from the overhead roadway arch. I used to go to the cinema when I was trying so hard to learn Italian ... Had no idea it was in the huge quarry. Do you know about the emergency exit? It is the long lighted tunnel that leads up the side of the green giant, heads up its left side, loops up, then back down and then turns basically West and exits onto rampa Brancaccio. Also, after the Metropolitan closed, it all remained vacant for a long time, then some promoters were going to put in a huge parking garage but that got defeated and the cinema multiplex finally was built, utilizing the huge central area of the quarry.
"...the narrow quarry that enlarges on its southern end in yellow right at the tip of your dotted line arrow was going to be a private gold mine after being converted to parking. During the Mussolini days, a shady entrepreneur was going to develop this into a large parking garage by having an access road cut somehow basically off the Santa Maria Capella Vecchia near the rampa Caprioli. The Duce and his boys nixed the deal."
