New technology had a great impact on architecture. Less man power was needed after cranes were made. People could build bigger and more complex buildings with the invention of the crane. Cranes could lift heavy materials to make taller and bigger buildings like the skyscrapers. 

The invention of lighthouses improved conditions for sailors to get to the ports safely and for more sea trade. Lighthouses provided landmarks for sailors and they helped  them look out for rocks so they don’t sink their ships. Before lighthouses there was no visible landmarks and at night sailors could not see the rocks until it was too late. Bigger ports were made and cities became wealthier because of the sea trade that  lighthouses made possible.

As you can see increased technology allowed for bigger buildings and helped increased trade and made bigger and wealthier cities.
