Located picturesquely on the eastern shore of Lake Iznik, the town bearing the same name might seem a backwater location with a laid-back ambience. However, the traces of mighty fortifications that greet the visitors to Iznik suggest that the town is much more than a sleepy settlement. Today's Iznik is, in fact, the ancient city called Nicaea, where the major events that shaped the future of Christianity took place. The town was once the summer residence of the Roman Emperor Constantine I the Great liked to spend the hot season because of the pleasant, mild climate.

The visitors who come to Iznik have a unique opportunity to see the monuments from all the periods of the town's rich history: magnificent city walls, ancient Roman theatre, and many churches and mosques, including the former Hagia Sophia Church, now serving as Ayasofya Mosque, where the Second Council of Nicaea was held in 787. The long and complicated history of the town and its surroundings is beautifully explained in two local museums — the first one is focussed on Iznik's prehistory and the history to the times of the Ottomans, and the second one — on its Islamic heritage.

The guidebook The Highlights of Iznik. Treasures of the ancient Nicaea starts by introducing the short history of Iznik, and then takes the readers on the journey throughout its most significant landmarks, historical buildings, and museums. The final chapter invites the visitors to step outside the mighty fortifications and discover three historical gems hidden in the countryside: an obelisk, an aqueduct, and a Byzantine bridge. The chapters about the sights of Iznik are equipped with geographical coordinates and QR codes that facilitate the sightseeing. The visit to the town will be much easier with the provided plan of the town and numerous colourful photographs offer the readers a glimpse of what's awaiting them in Iznik.

The book is available from Amazon as paperback and as Kindle ebook. Ebook is also available from Google Play Books.
