Oxford street is one of the busiest streets in London . It is a shopping destination to various well known brands. The place appears in North and South when the coach heads to Milton he most likely came across this street. 

It is well known to be a high priced shopping destination that maybe in the 1800's was one of the biggest markets in London were people did their trades. The street was completed in 1825 and was one of the first devolpments in UK. There are many events were held on this strret such as yearly festival and fashion and design month. 

Knowing about this place helps me understand the novel north and south because back then this was one of the first devolpments were churches are houses were getting built , therefore it creates a civilization and with the industrial revolution shop opened and selling and trading goods.
