At the beginning of this week I was on holidays in Istanbul and during this time nine postcards arrived including one from Estonia.
It shows the Tahkuna Lighthouse on the island of Hiiumaa. The Tahkuna Lighthouse was built between 1873 and 1875. With a height of 43m it is the tallest cast-iron tower in Estonia.
With a matching stamp and another nice stamp:
Otter (issued 25-08-2015)
Tahkuna Lighthouse (issued 16-10-2015)
with First Day Special Postmark
Definitive (issued 16-10-2015)
Thank You very much Jaan!
