Possibly the most celebrated cathedral in the world, the Duomo as it is simply known in Florence is the jewel of the city.It was initially constructed in 1436, but the astonishing front facade wasn’t completed until the 19th century.Located in the centre of the old city, the Duomo stands out for miles and creates an imposing sight amongst the other medieval buildings.The exterior and front facade of the Cathedral are monumental – covered in white marble and red, pink and green polychrome designs; the colour and style is breathtaking.Furthermore, an immense dome sits at the read of the cathedral and can be accessed via a series of steps.Although the interior of the cathedral is quite bare in contrast, it still speaks of grandeur and has several interesting pieces such as the large clock face and the magnificent Last Judgement fresco that covers the underside of the dome.
