Whilst there are fewer tourists around at the moment I am visiting as many of the local tourist attractions as I can. A couple of weeks ago I was at the CosmoCaixa, the science museum, then I visited the Palau de la Musica.
My most recent visit was to Casa Vicens, last week.
This was Gaudi's first building work and up until a few years ago was a private residence. Lucky for us it's now open to the public.
It's only small so the tour around it isn't too long, I took about an hour, and with the informative audioguide, which you can download to your phone on arrival in a wide range of languages, it is a pleasure to wander the rooms listening to interesting info about each one.
I paid €16 for entry, and it was money week spent. I am a fan of Gaudi's work and this really is a little gem.
There is even a copy of Gaudi's notebook for the project
From Vilanova the easiest way to arrive is by train to Barcelona Passeig de Gracia, then walk up hill (about 25 minutes) into the Gracia Barrio, which itself is worth wandering around if you have the time.
