well, moscow has st. basils (did i say it right?) and the kremlin, something ive been dieing to see my whole life. st. petersburg has many monument to tsar peter the great, and i think it located on a sea. for age, i would definatly go to volgograd (i think thats teh ancient one). for extreem cold, id go to yakutsk, that place has like -65 tempratures, or it did last week.
