The spiralling twin towers of this ancient church witnessed many of the tumultuous events that have shaken the city of Krakow over the centuries. The top of the church tower is a perfect spot to take some beautiful photos of the city.

When it comes to architecture in Glasgow, Charles Rennie Mackintosh is the name you'll hear time and again. Best known for his work in the Art Nouveau style, Mackintosh left an indelible mark on the city, with the 1898 Glasgow School of Art as the crown jewel. Nowadays, the school isn't just about educating the next generation of artists — it's also about appreciating its rich history.

Built on the remains of the old Moorish mosque, the building started out as a Parish Church, ascending in importance, as Archiprestal (1281), Collegiate (1413) and finally becoming a Cathedral in 1510. Building started at the end of the 13th Century. It is of Levantine Gothic Style, with three naves and a gallery, a transept transformed by Pere Compte at the beginning of the 16th Century and side chapels between the buttresses. Of note inside is the ironwork, the Baroque organ, the work of Jacinto Perales and the choir stalls, made by Juan Bautista Borja and Tomás Llorens (1716-1718). The sacristy is home to the relics cabinet and cupboard, the work of José Ganga (1732-1734), holding diverse relics within a carved bust. On the outside, of note in the Tower, built between the late 13th Century and the mid-14th Century, the same as the three main gateways, The Puerta de Cadenas (14th Century), Puerta de Loreto (15th Century) and finally, the Portada de la Anunciación, completed by Juan Inglés in 1558.
