The whole site of the works has been reclaimed from the sea, and a great sea-wall was built to form the southern boundary of the docks, the number of which was increased from one to three.
On the west the coast is mostly either a steep rocky declivity or a sea-wall, though strips of lower ground are found in the bays.
The Western Ghats form the great sea-wall of the Bombay presidency, with only a narrow strip between them and the shore.
In certain states of wind and sea it is turned almost into an island, and a sea-wall protects the road to Saffi.
Another improvement is the extension of the sea-wall southward from the ferry-slips (Praga 15 de Novembro) to the Ponta do Calabougo (war arsenal), providing protected basins for the arsenal and enclosing small reclaimed areas.
