Yesterday night I attended a 2-hour seminar organised by the School of Continuing & Professional Studies of the Chinese University of Hong Kong. The host has been traveling to Barcelona and Madrid so he introduced the art works and architectures by famous artists and architects like Antoni Gaudi, Pablo Picasso, John Miro, Salvador Dali, Velasquez, Diego and Goya. I have been to Spain and I was really impressed by the architectures by Antoni Gaudi. I hope that I shall go to Barcelona again as I have not had enough time on exploring the city last time.
Las Meninas - Diego Velazquez (More description of the above artworks at Wikipedia) I remember that I have seen it in person when I was in Spain years ago!)
