Anything from a Cathedral to a bridge

Wesminster Abbey.

Probably St. Isaac's Cathedral in St. Petersburg, Russia. Though there is something about the Eglise du Dome in Paris that I love, perhaps the beauty of the building combined with the wierdness of Napoleon. Oh, and Saint-Mere Eglise in Normandy, with the stained glass windows of american paratroopers coming into France, that window really touched me.

Three way tie: Monument A Vittorio Emanuele in Rome; the Cathedral in Seville and the Grande Arch La Defense in Paris.

Hard to pick only one but I love Ste. Chappelle in Paris, the Palazzo Vecchio in Florence and the Bovolo staircase in Venice. The Palazzo Vecchio is a favorite because of its setting.

The Pantheon in Rome,the Colosseum,Piazza di Spagna, the Duomo in Milano , Notre Dame in Paris, Saint Denis Cathedral, Ponte Vecchio in Florence and many others places..

The Duomo in Florence?

The Duomo in Milan?

Phaistos palace?

Ruins that haunt me:

1)the Roman library of Celsus at Ephesus
2)the Norman-Arabic pleasure palace La Zisa in Palermo
3)the sod houses of the Nebraska plains.

Chenonceau, Ste. Chappelle, Chartres, Vienna Rathaus, Pont Alexandre III, the list is endless!

It would be hard to pick a "favorite" but Monastery of Jernimos in Lisbon Portugal is very high on my list! It was worth the trip to Lisbon.

Ya know, it's just kind of hard to beat St. Peter's. Perhaps I should change my name to "Mr. Obvious" for this thread.

Also, I have to give props to the Chateau de Chenonceaux (sp?), which is one of my favorite castles AND one of my favorite bridges, all in one.

Matisse's chapel in Vence

Notre Dame du Haut, Ronchamp by Le Corbusier.

The Zwinger and Frauenkirche (Dresden).

Ste. Chappelle
Chenonceau
Melk Abbey
Weiskirche

to name some

Parliament in Vienna, Fisherman's Bastion in Budapest, Spanish Steps in Rome, and all the lovely baroque buildings in Prague.

The Opera Garnier in Paris and Lloyds of London.

From my first up-close visit to my most recent, I remain in awe of the elegant ironwork of Gustave Eiffel's magnificent tower.

For smaller buildings, I love Gaudi's Casa Batlo in Barcelona, particulary stunning at night.

Not very original, but the Pantheon in Rome, especially during a thunderstorm.
