The construction of the square begins in 1729, by order of Phillip V, with the square being meant primarily for bull fights. Today, it is seen as one of the most beautiful squares in Spain and in the whole of Europe. The space offers a paradoxical optical illusion. It seems a perfect quadrangle, although, as seen from an aerial photo, the shape is irregular. The baroque façades of the building, which surrounds and defines the square perimeter, seem perfectly symmetrical on a first glance, but, in reality, not one of them has the same height. Entire books have been written about the square in Salamanca, and, to this day, it is considered the absolute model of Spanish squares.
Founded in 1354, on the spot where, in a thick forest, two roads crossed next to waterways at the border between Moravia, Bohemia and Austria, Tel, called Teltsch in German, has the misfortune of experiencing a great fire two centuries later. The city is quickly rebuilt following the old plan, but with modifications which take into account the evolution of building styles and techniques. The Gothic castle is remade in Renaissance style and the lofts are built for the houses in the square. The houses receive painted façades, then later replaced in the 18th century with rococo and baroque ones. The medieval Gothic arch on the ground floor remains unchanged. It is continuous, all the houses in the square are united by it. Two churches will be built and a plague column will be dedicated to Saint John Nepomuk, flanked by two fountains. Towards the end of the 18th century time suddenly stops in Tel, with the end of its glory age and of its economic development. The city reaches our times without changes, unaffected by industrialisation and, through some miracle, without socialist blocks. It is straight out of a book of folk tales. The map of the city is practically synonymous with the triangular square. One step outside of it carries you to the yellow canola fields of the Bohemian hills.
