Lahti is a city in Finland. It is the main city of the Päijät-Häme region. Lahti is located in the Finnish Lakeland, a beautiful area with many lakes. About 121,000 people live in Lahti. It is one of the biggest cities in Finland.
The city sits on a bay at the southern end of Vesijärvi lake. It is about 100 kilometres (60 mi) northeast of Helsinki, the capital of Finland. Lahti is an important meeting point for two major highways. These roads connect it to other big cities like Jyväskylä, Tampere, and Kouvola.
The Finnish word "Lahti" means bay. The city is sometimes called the "Chicago of Finland." This is because both cities grew with industries like meatpacking. Also, both cities had some tough times with crime in their early days.
Lahti is a leader in protecting the environment. It has been working on sustainability since the 1990s. The European Commission even named Lahti the European Green Capital for 2021.
Lahti is also home to the Salpausselkä UNESCO Global Geopark. This is one of four UNESCO Geoparks in Finland. It was added to the list in 2022.
The city's coat of arms shows a train wheel with flames. This design represents the Riihimäki–Saint Petersburg railway. This railway was very important for Lahti becoming a city.

History of Lahti
Lahti was first mentioned in old papers in 1445. It was a small village that belonged to the parish of Hollola. The village was on an old trade route that connected Hämeenlinna and Viipuri.
In 1870, the Riihimäki – St. Petersburg railway line was finished. A year later, the Vesijärvi canal was also completed. These new transport links made Lahti a busy place. Factories and industries started to appear around the railway station. For a long time, the station at Vesijärvi Harbour was the second busiest in Finland. Many workers, craftsmen, and merchants moved to the area.
On June 19, 1877, a big fire burned almost the entire village. But this accident actually helped Lahti grow. It made the authorities decide to officially make Lahti a town. In 1878, Emperor Alexander II of Russia gave Lahti the right to hold a market. A new town plan was approved. It had a large market square and wide streets. This plan is still the basis of the city center today. Most early buildings were small wooden houses.
Lahti became a city during a difficult economic time. The Russian Empire was fighting a war, which affected Finland's economy. This slowed down building in Lahti. Land was hard to sell, and many plots stayed empty. In its early years, the town had only about 200 people. It was too small for much trade.
By the late 1890s, Lahti's leaders worked hard to make it a city. In 1904, their efforts paid off. The Senate approved the idea. Then, Tsar Nicholas II finally gave his approval. Lahti officially became a city on November 1, 1905.
By the end of 1905, about 8,200 people lived in the Lahti area. Nearly 3,000 of them lived in the new city. Essential public buildings like a hospital and city hall were built quickly. More brick houses started to appear in the city center. In 1918, the Battle of Lahti took place during the Finnish Civil War. German troops took the city from the Red Guards.
In the early 1920s, the city gained control of the Lahti Manor land. This land was important because it connected the city to the lake. Industries grew fast in the 1930s, and the population increased. Lahti was one of Finland's fastest-growing cities. Before World War II, nearly 30,000 people lived there.
Lahti continued to grow by adding new areas in 1924, 1933, and 1956. The population grew a lot after WWII. About 10,000 people who had to leave their homes were settled in Lahti. More people moved to the city in the 1960s and 1970s. This fast growth slowed down in 1975. However, Lahti grew again in 2016 when the nearby area of Nastola became part of the city.
In December 2018, Lahti became Finland's newest university city. This happened when the Parliament changed the university law. Now, LUT University has two campuses: one in Lappeenranta and one in Lahti.
Geography and Climate

Lahti's landscape is shaped by the Salpausselkä ridge. This long hill runs through the city from west to east. North of the ridge, you'll find rocky hills and many small lakes. South of it, there are more forests and small rivers. The soil also changes: it's mostly rocky in the north and clay in the south.
The largest lake is Vesijärvi. It's a gateway to Central Finland through Lake Päijänne. There's also a smaller pond called Pikku-Vesijärvi ("Little Vesijärvi") near the Lanu-puisto park.
