Lithuania is the southernmost of the three Baltic states with around 2.8 million inhabitants. It borders the Baltic Sea to the west and shares borders with Latvia, Belarus, Poland and the Russian Kaliningrad region. The country has been a member of the European Union and a member of NATO since 2004. Since 2015, people have been paying with the euro there.

The capital and largest city of Lithuania is Vilnius, other major cities include Kaunas, Klaipeda and Siauliai. The population has been decreasing continuously since the end of the Soviet Union in 1990, due to constant emigration and the excess number of deaths.

Around 2 million tourists come to the country every year, most of them from Russia. The main tourist destination in Lithuania is Vilnius with its impressive old town.

Around 570,000 people live in the capital, it is also the largest city in the country and even the largest city in the Baltics in terms of area. In 2009 the city was the European Capital of Culture. The old town of Vilnius is one of the largest in Eastern Europe and has therefore been a UNESCO World Heritage Site since 1994. There are over 50 churches in the city and it is therefore nicknamed the “Rome of the East”. The sights in the old town include the Castle of Gediminas, the Grand Prince's Castle, the Roman Catholic Cathedral of Saint Stanislaus, the Church of St. Francis, the Church of St. Anne, the Choral Synagogue, the baroque university complex with the St. John's Church, the baroque Casimir Church, the old town hall, the Orthodox Cathedral of the Assumption of the Mother of God, the Catholic Holy Spirit Church and the Gate of Dawn.

Outside the old town is, among other things, the Europa Tower, the tallest skyscraper in the entire Baltics.

The only time I ever visited Lithuania was in June 2012. Coming by bus from Riga, after a 2-day stay in Vilnius we continued to Minsk in Belarus. The Baltics are really very easy to travel around by public transport. The buses are all ultra-modern and inexpensive, equipped with free internet and even a VIP compartment. The journeys between the Baltic capitals never last more than 5-6 hours and cost a maximum of 20 euros.

In Vilnius I took a central, inexpensive hotel and then spent the whole day exploring the entire old town and almost all of the 50 churches. First in a restaurant and then in one of the many bars, I ended the evening in the wonderful old town.
