This card is from the same RR as the Switzerland card I just posted. I seem to be receiving quite a lot of lighthouse postcards from Estonia nowadays. Not that I mind - they are all lovely!
Pärnu is the summer capital of Estonia and the main city of the Pärnumaa region. There are two breakwaters in the mouth of Pärnu River. The one on the left bank (Pärnu Mole) has become the symbol of Pärnu.
Have I mentioned that I really like Estonian stamps? Well, I do. :) The one on the right was issued in 2007 and shows St John's of Kanepi Church. I couldn't find any info on the second stamp but it's pretty old - issued in 1996! It shows Guglielmo Marconi, an Italian inventor best known for his development of a radio telegraph system.
