Look for an image of a building that you think incorporates characteristics of Classical, Gothic, or Renaissance architecture. Copy and paste the image or a link to the image into the discussion thread, and explain how you believe the building you chose has Classical, Gothic, or Renaissance characteristics. Cite specific features, such as the use of columns, arches, flying buttresses, and so on. Decide which architectural style you prefer, and explain why. Here are some ideas for providing a photograph of a building:

Search the Internet. Copy and paste the image or a link to the image into the discussion thread.
Look through books and magazines. Take a photograph of the building or scan it, then copy and paste the image into the discussion thread.
Search for a building close to where you live. Take a photograph of the building, and then copy and paste the image into the discussion thread.
