Scotland's capital is famous for its stone tenements and they come in all kinds of different styles, sizes and even colours - and in some areas of the city, the contrast is quite spectacular.
Take the foot of Montpelier Park, just off Bruntsfield Place, for example, where blonde sandstone tenements rub shoulders with vibrant 'redheads'. The reason behind this architectural quirk is rather fascinating.
The first sandstone tenements in Edinburgh rose in the early 1800s to accommodate a population that was growing fast and to unprecedented levels.
