The term 'SITE OF A TILTED TOWER' can be summarized as the city of Pisa, which is a four-letter word. Pisa is an Italian city located in the Tuscany region and is most famous for its iconic leaning tower. The Leaning Tower of Pisa is a freestanding bell tower that began to lean during construction in the 12th century due to an inadequate foundation on ground too soft on one side to properly support the structure's weight. Despite numerous attempts to fix the tilt, the tower still leans at an angle of 3.99 degrees. It is now a UNESCO World Heritage Site and a major tourist attraction.
