This week Alastair Sooke and Janina Ramirez’s ‘flying visit’ is to Barcelona, where art historian Janina looks at the city’s Roman past while Alastair explores more recent buildings such as Gaudí’s Casa Batlló.

He and Janina also visit the Catalan architect’s Sagrada Família and the Torre Bellesguard.

Janina has a moan about tourists (Alastair calls her a snob) but, unlike other travelogues which show presenters getting VIP access, the strength of this series is you can do pretty much everything these two do.
