York is one of the oldest cities in England, and it is said that to visit York is to experience a thousand years of history : the history of York is the history of England. The slideshow above follows the walls from Petersgate to Layersthorpe and covers roughly 1.3 miles. The entire walk, though no longer viable is about two miles all the way round.

The traditional cuisine of Yorkshire, in common with the North of England in general, is known for using rich tasting ingredients, especially with regard to sweet dishes, which were affordable for the majority of people.
There are several dishes which originated in Yorkshire or are heavily associated with it. Yorkshire pudding, a savoury batter dish, is by far the best known of 
Yorkshire foods, and is eaten throughout England. It is commonly served with roast beef and vegetables to form part of the Sunday roast but is, more traditionally served as a starter dish filled with onion gravy. Toad-in-the-hole is a dish that involves sausages and Yorkshire pudding batter baked together which is also served with an onion gravy.
Other foods associated with the county include Pikelets, which are similar to crumpets but thinner, Parkin, a sweet ginger cake which is different from standard ginger cakes in that it includes oatmeal and treacle and Wensleydale cheese, a cheese associated with Wensleydale and often eaten as an accompaniment to sweet foods.
Yorkshire and in particular the city of York played a prominent role in the confectionery industry, with chocolate factories owned by companies such as Rowntree’s, Terry’s and Thorntons inventing many of Britain’s most popular sweets.
York has a large number of pubs and ale-houses, a couple dating back as far as the fourteenth century, within its extensive walls. Brewing has taken place on a large scale since at least the 12th century, for example at the now derelict Fountains Abbey which at its height produced 60 barrels of strong ale every ten days. Most current Yorkshire breweries date from around the time of the Industrial Revolution of the late eighteenth and early 19th century.
Therefore it also has its fair share of breweries including Black Sheep, Copper Dragon, Cropton Brewery, John Smith’s, Sam Smith’s, Kelham Island Brewery, Theakstons, Timothy Taylor and Leeds Brewery.
