About the Photo:
It was used as the background for a poster of a help line for students (against suicide).
I took it in May 2006 during the parade of Queima das Fitas. I already uploaded a shot taken in the end of those parades. It's one of the things I love shooting the most. Right next to performance and kittens. :)
So here's some background on it:
Info from wikipedia:
Coimbra is called as A cidade dos estudantes (The city of the students), mainly because it is the site of the oldest and one of the most prestigious universities in Portugal - the University of Coimbra. It is also the place where the oldest and biggest students' union of university students in Portugal was founded - the Associação Académica de Coimbra. Besides that, there are also some other smaller schools and institutes of higher education in the city: the Instituto Politécnico de Coimbra, a polytechnic institute; two nursing schools and some private higher education institutions such as the Instituto Superior Miguel Torga; the Instituto Superior Bissaya Barreto; the Escola Universitária Vasco da Gama and an arts institute. The city has also a large number of public and private basic and secondary schools, as well as kindergartens and nurseries.
Coimbra is also known for its university students' festivals. Two are held every year.
The second one, Queima das Fitas (The Burning of the Ribbons), more important than the first, takes place at the end of the second semester (usually in the beginning of May) and it is one of the biggest student parties in all Europe. It lasts for 8 days, each for each University of Coimbra's Faculty: Letras (Letters), Direito (Law), Medicina (Medicine), Ciências e Tecnologia (Sciences and Technology), Farmácia (Pharmacy), Economia (Economics), Psicologia e Ciências da Educação (Psychology and Education Sciences) and Ciências do Desporto e Educação Física (Sports Sciences and Physical Education).
Although being University of Coimbra festivals, other higher education students of Coimbra such as the polytechnic students or private institution students, are invited every year by the University of Coimbra students who manage and organise this events, to participate in the Tin Can Parade and also in the Burning of the Ribbons.
