Q: Valencia was founded as a Roman colony in 138 BC. The city is situated on the banks of the Turia, on the east coast of the Iberian Peninsula, fronting the Gulf of Valencia on the Mediterranean Sea. Its historic centre is one of the largest in Spain, with approximately 169 hectares; this heritage of ancient monuments, views and cultural attractions makes Valencia one of the country's most popular tourist destinations. Major monuments include Valencia Cathedral, the Torres de Serrans, the Torres de Quart, the Llotja de la Seda (declared a World Heritage Site by UNESCO in 1996), and the Ciutat de les Arts i les Ciencies (City of Arts and Sciences), an entertainment-based cultural and architectural complex designed by Santiago Calatrava and Felix Candela. The Museu de Belles Arts de Valencia houses a large collection of paintings from the 14th to the 18th centuries, including works by Velazquez, El Greco, and Goya, as well as an important series of engravings by Piranesi. The Institut Valencia d'Art Modern (Valencian Institute of Modern Art) houses both permanent collections and temporary exhibitions of contemporary art and photography.

Q: In the north Eristov pushed southwest, fought two battles, forced the Turks back to Batum, retired behind the Cholok River and suspended action for the rest of the year (June).

Both slowly approached along the Kars-Gyumri road and faced each other, neither side choosing to fight (JuneJuly). On 4 August Russian scouts saw a movement which they thought was the start of a withdrawal, the Russians advanced and the Turks attacked first. They were defeated, losing 8000 men to the Russian 3000. 10000 irregulars deserted to their villages. Both sides withdrew to their former positions. About this time the Persians made a semi-secret agreement to remain neutral in exchange for the cancellation of the indemnity from the previous war.
