... the LTTA to Portugal ended up with  a touristic visit in Porto,

including a guided tour at the traditional Ferreira’s wine cellars

which are located on the banks of the River Douro, in the historic centre of Vila Nova de Gaia (opposite to Oporto city), in a vast and historic building that dates back to the start of the 18th century.

... the tour in Porto  continued by visiting some of the landmark points as 

the Porto Town Hall

the Igreja Santa Clara, a Portuguese Baroque religious monument dated  600 years back,

... and the Douro River banks of course
