Nesebar (often transcribed as Nessebar and sometimes as Nesebur, Bulgarian: Несебър, pronounced [nɛˈsɛbɐr], Thracian:Melsambria, Greek: Μεσημβρία, Mesembria) is an ancient town and one of the major seaside resorts on the Bulgarian Black Sea Coast, located in Burgas Province. It is the administrative centre of the homonymous Nesebar Municipality. Often referred to as the "Pearl of the Black Sea", Nesebar is a rich city-museum defined by more than three millennia of ever-changing history.

It is one of the most prominent tourist destinations and seaports on the Black Sea, in what has become a popular area with several large resorts—the largest, Sunny Beach, is situated immediately to the north of Nesebar.

Nesebar has on several occasions found itself on the frontier of a threatened empire, and as such it is a town with a rich history. The ancient part of the town is situated on a peninsula (previously an island) connected to the mainland by a narrow man-madeisthmus, and it bears evidence of occupation by a variety of different civilisations over the course of its existence. Its abundance of historic buildings prompted UNESCO to include Nesebar in its list of World Heritage Sites in 1983.

Paphos /ˈpæfɒs/ (Greek: Πάφος [ˈpafos]; Turkish: Baf) is a coastal city in the southwest of Cyprus and the capital of Paphos District. In antiquity, two locations were called Paphos: Old Paphos[2] and New Paphos.[3] The currently inhabited city, New Paphos, lies on the Mediterranean coast, about 50 km (31.07 mi) west of Limassol (the biggest port on the island), which has an A6 highway connection. Paphos International Airport is the country's second-largest airport.

Near Palaepaphos (Old Paphos) at the seaside of Petra tou Romiou is the modern mythical birthplace of Aphrodite, theGreek goddess of love and beauty, and the founding myth is interwoven with the goddess at every level, so that Old Paphos became the most famous and important place for worshipping Aphrodite in the ancient world. In Greco-Roman times, Paphos was the island's capital, and it is well known for the remains of the Roman governor's palace, where extensive, finemosaics are a major tourist attraction. Paul the Apostle visited the town during the first century AD. The town of Paphos is included in the official UNESCO list of cultural and natural treasures of the world's heritage.

The Historic Centre of Riga boasts the largest collection of Art Nouveau buildings in Europe. Between 1896 and 1913, the city expanded and a housing boom followed. The style which developed in Riga was influenced mainly by German, Austrian and Finnish architects. Mikhail Eisenstein is one of the most famous proponents of the style in Riga. 

After the revolution of 1905 a distinctively Latvian variation of Art Nouveau developed, known as National Romanticism. Architects started to use traditional Latvian folk elements and natural building materials. Typical elements were steep roofs, heavy structures and the use of ethnographic ornamental motifs. 

Riga as a city made its first mark in history in the 1201. In that year, Albert the Bishop of Bremen established his first German fortress here. With his Knights of the Sword he executed a Crusade to the Baltics. The town started to prosper as a trading station. This resulted in joining the Hanseatic League in 1282.
