<a class="linkToPlace" target="_blank" href="/place?placename=New Carthage&groupId=791&placeId=1430">New Carthage</a> lies half way down the coast of <a class="linkToPlace" target="_blank" href="/place?placename=Spain&groupId=983&placeId=1735">Spain</a>, in a gulf which faces south-west and is about twenty stades long and ten stades broad at the entered. This gulf serves as a harbour for the following reason.
At its mouth lies an island which leaves only a narrow passage on either side,
and as this breaks the waves of the sea, the whole gulf is perfectly calm, except that the south-west wind sometimes blows in through both the channels and raises some sea.
No other wind, however, disturbs it as it is quite land-locked. In the innermost nook of the gulf a hill in the form of a peninsula juts out, and on this stands the city, surrounded by the sea on the east and south and on the west by a lagoon which extends so far to the north that the remaining space, reach as far as the sea on the other side and connecting the sea with the mainland, is not more than two stades in breadth.
The town itself is low in the centre, and on its southern side the approach to it from the sea is level. On the other sides it is surrounded by hills, two of them lofty and rugged, and the other three, though much lower, yet craggy and difficult of access.
The biggest of these hills lies on the east side of the town and juts out into the sea, and on it is built a temple of Aesculapius.
The second is opposite it on the western side in a similar position, and on it stands a magnificent palace said to have been built by Hasdrubal when he aspired to royal power.
The three other smaller eminences are to the north of the city,
the most easterly being called the hill of Vulcan, the next one the hill of Aletes, who is said to have received divine honours for his discovery of the silver mines, while the third is known as the hill of Saturn.
An artificial communication has been opened between the lagoon and the neighbouring sea for the convenience of shipping,
and over the channel thus cut through the tongue of land that separates lagoon and sea a bridge has been built for the passage of beasts of burden and carts bringing in supplies from the country.
