We visited a lot of mosques during our time in Istanbul, most of which were centuries-old architectural masterpieces built by the Ottomans. But Islam is very much a modern religion, so we felt compelled to check out a couple of the city's contemporary mosques, one in Kadiköy and the other in Umraniye.
Even more "orient" than the Orient Express, the Baghdad Railway connected the future capital of Iraq to Istanbul. The western terminus was the massive Haydarpaşa Station, which is still one of the busiest train stations in Turkey. We spent a day exploring the magnificent old station and the neighborhood surrounding it.
