The compass, designed by Cristino da Silva is 164 ft (50m) in diameter.  It is most impressive when seen from the Discoveries monument’s observation deck.

There are two main styles of Port: those aged in oak barrels and those matured in a bottle. The top of the Port hierarchy is the vintage Ports, having great power, flavor, and complexity. Some top picks include Taylor’s Vintage Port 1985, Warre’s Vintage Port 2000, Quinta Do Noval Nacional Vintage Port 1985, Fonseca Guimaraens 1998, Graham’s Vintage Port 2003, Niepoort Colheita Port 1995, and Dow Vintage Port 1975, among many others. If you're at Mercado da Ribeira, Garrafeira Nacional has a great selection of Port and other wines.
