There is plenty to see in the Portuguese city of Porto (OPO). The numerous port houses are a popular tourist attraction. The Port and Douro Wines Institute, which is located in the city centre, is responsible for the quality of the wines. Porto's breathtaking and elaborate 12th-century cathedral, Sé do Porto, is a symbol of the city and an absolute must-see.
Jardim do Passeio Alegre is a wonderful park and ideal for romantic walks. The oldest city park in Porto is Jardim de São Lázaro. In addition to old trees, there are also historic monuments in this park.
