As has become Sant Jordi tradition, Palau Güell joins in on the celebration of the city's patron saint with an Open Day and a stall on La Rambla. Tickets to get in to the Gaudí-designed palace are given out starting from 10am and again from 3pm until they run out. The last admittance of the day will be at 7pm. What's new this year is that on April 22 the Palau organises a tour and a family workshop called 'The Rose: ornamentation at the Palace and stamping'. After taking a child-friendly guided tour through the most floral corners of the palace, your little artists will stamp and paint their flower motifs using engraving and stamping techniques.
