The picture on the left above shows part of the façade of the Panthéon. The picture on the right shows the view down the rue Soufflot from the "balcony" of the Panthéon. That's the palais du Luxembourg and its famous garden at the end of the rue Soufflot, where it intersects the boulevard St-Michel and, of course, the Eiffel Tower in the distance. This was a great neighborhood to be working in back in the 1970s, when I was first living in Paris.
This is the front entrance to the Pantheon, with all those columns. The people in the picture give you a idea of the scale of the place. The photo on the right shows the cupola inside the building, under the Panthéon's huge dome.
Finally, on the left just above is the famous "balcony" that I've mentioned several times over the past few days. That's the observation deck, which is also surrounded by a huge colonnade.You can see it under the dome in the photo above these. It's where I was taking pictures from. On the right is another interior view — more massive columns.
