Predominately agricultural and pastoral, the Peloponnesus produces currants, grapes, figs, citrus fruit, olives, tobacco, and wheat. The most fertile parts of the peninsula are the coastal strips in the north and west. Sheep and goat raising, textile manufacturing, fishing, and sericulture are major sources of income. There are deposits of pyrite, manganese, lignite, and chromium. The peninsula attracts many tourists; the port cities of Pátrai, Corinth, Kalamata, and Návplion are the main modern centers of the Peloponnesus.
