From Horizon’s commentary:
The unique blue tiles of Isfahan’s Islamic buildings, and the city’s majestic bridges, contrast perfectly with the hot, dry Iranian countryside around it, Isfahan is a sight you won’t forget. Not only is the architecture superb and the climate pleasant, but there’s a fairly relaxed atmosphere here, compared with many other Iranian towns. It’s a city for walking, getting lost in the bazaar, walking in beautiful gardens and meeting people.
The famous half-rhyme Isfahan nesf-e-jahan (Esfahan is half the world) was coined in the 16th century to express the city’s grandeur. There’s so much to see that you’ll probably have to ration your time and concentrate on must-sees such as the Imam Mosque, a magnificent building completely covered in Isfahan’s trademark pale blue tiles; This mosque is situated to the south of Naqsh-e-Jahan sq. built in the reign of shah Abbas, tile work and architecture of this Mosque is amazingly superb. Its minarets Are 48 meters high. Naghsh-e-Jahan (world picture) Square, one of the largest town square in the world. The Chehel Sotun Museum & Palace, a marvellous 17th century pavilion and a great place for a picnic; this palace is another building dating back to the Safavid period, built amidst a vast garden covering an area of 67000 sq m. The building has a veranda with 18 pillars and a large pool in front of it. Being mirrored in the still water of the pool, the pillars create a beautiful view. The wall painting in the interior of the building is superlative in their kind.Ali Qapoo Palace Situated to the west of Naghsh-e-Jahan Sq. belongs to the Safavid period. It was used for the reception of the Ambassadors and envoys from other Countries. Ali Qapoo is a six-storied plasterwork and paintings of which are extremely impressive. and the Vank Cathedral, the historic focal point of the Armenian church in Iran. Taking tea in one of the teahouses under the bridges is also an essential part of the Isfahan experience.
