Porto, Portugal - May 3

Porto (Leixões), Portugal -  May  3

Portugal's second-largest city, where port wine mixes beautifully with strolls past historic architecture. Shops up and down the lanes of the historic Old Town invite window shopping. 

The imposing Romanesque Cathedral commands more than just a passing glance with its towering facade.

Along the Douro River, the prosperous fate of Porto was sealed when the barcos rabelos delivered the first wine shipments here from vineyards upriver. These vessels still bob with the current. 

Across the river, and over the distinctive 19th-century Dom Luis | Bridge, cellars of 58 companies fortify the prized port wine that is still produced in the Douro Valley.

Worlds largest concrete arched bridge.

Barcos rabelos now carry tourists rather than port wine
