London in the 1600's was much different than London today. They didn't have any sewage systems so they would throw their waste into the streets and alleyways. Houses were made of mostly timber and nobility had houses made of brick and hard stone. There weren't many hallways in houses. Usually rooms just opened directly into another room. London's streets were made of cobblestone and people crossed the river by boats. Plays at the Globe Theater were big events. There were vendors near the theater selling souvenirs and food like pickled pig feet. In the Globe Theater there were no seats, everybody stood.
In London today things are very different. Now they have modern sewage systems. Another modern change is that roads in London today are paved and not made out of cobblestone. Houses in London that are newer or have been renovated have hallways and man made building materials. Modern roads in London today are paved instead of being made out of cobblestone. Instead of using boats to cross the river there are bridges that people can drive cars over like the London Bridge and the Millennium Bridge. The Globe Theater was closed in 1642. However, more modern theaters have seats including balconies. Theaters still sell concessions but they no longer sell pickled pig feet. Instead they sell small snacks. Even though theaters sell concession and souvenirs there are not big markets.
