Patkuli Viewing Platform is where the true beauty of Tallinn really shines. From this viewpoint, you will be able to see not only the beautiful vibrant roofs of Tallinn's houses but also all the old medieval stone towers, walls, and the spire of St Olaf's church all at once which is quite a sight to behold.

To get to the viewpoint, you can either walk up the 157 steps from the bottom of the cliff via Patkuli Stairs or you can take the more scenic route around and through the Old Town which should take you through some of the most beautiful attractions in Tallinn. There is no closing time at the viewpoint as it is simply a platform along the cobblestone street right by the cliff. Plus, there is no entrance fee whatsoever so you can visit any time you like.

Tallinn Town Hall is the heart of Tallinn Old Town and it is one of the best places to hang out in Tallinn. Surrounding the Town Hall is a large square full of restaurants and cafes where people like to congregate. The Town Hall itself is pretty incredible as well as it is believed to be the oldest city town hall in Northern Europe. The Town Hall was constructed all the way back in the 13th Century and it still retains its unique Gothic architectural style after over 700 years.

The town hall itself is open only 2 months a year in June and August so if you are there in the right month, you can check out the interior for around 5 EUR per person. If not, you can also spend some time here and stroll around Town Hall Square, indulge yourself in all the restaurants and cafes, and admire all the colorful European-style houses surrounding it.

If you are into medieval history and ruins then you are going to want to spend some time and stroll around the old bastion passages starting from Kiek in de Kök Museum. The museum forms a complex of over 500 meters long and you will have access to the 4 medieval towers as well as the mysterious underground bastion passages that were constructed in the 17th Century which were used as another line of defense for the city connecting with the walls and towers you see around Tallinn.

To get to the bastion passages, you will have to pay around 12 EUR to enter the passage through Kiek in de Kök Museum. You will also have access to the towers and other parts of the museum as well with this ticket. The museum opens from 10 AM - 5 PM every day with the opening hours extended to 8 PM every Thursday. The museum is closed on Monday.

One of the prettiest cathedrals you will see in Tallinn is Alexander Nevsky Cathedral, a stunning onion-domed Russian Orthodox cathedral constructed at the top of Toompea Hill dominating the skyline of Tallinn's Old Town. This Orthodox church was built in 1900 when Estonia was part of the Russian Empire as a way to extend its influence over the increasingly unruly Baltic territory.

Despite its oppression symbolism, the city never managed to demolish the structure after it gained independence and it had since been turned into one of the most important landmarks in the city that you can visit. The cathedral is packed with mosaics and icons as well as a stunning golden altar at the center despite its small interior. If you are in Tallinn's Old Town, don't forget to visit the cathedral and admire its stunning beauty. The cathedral opens from 8 AM to 6 PM every day and it is free to enter.

Another church you should visit in Tallinn's old town is St. Nicholas' Church and Museum, an old medieval church originally constructed in the 13th Century before it was bombed by the Soviets and restored again after the war. Nowadays, it has since been converted into a museum to store all the ecclesiastical art from the Middle Ages onward that you can visit and learn a bit more about Tallinn's past.

Inside, you will find all kinds of exquisite medieval artifacts and religious artworks including one of the most famous religious artworks of all, Danse Macabre or the Dance of Death by Bernt Notke depicting the transience of life, the skeletal figures of Death, and the feeble ones. St. Nicholas' Church and Museum's opening hours are between 10 AM and 6 PM every day except Monday and the entrance fee is 8 EUR per person.

Toompea Hill has always been the core of power in Estonia. Various rulers of Estonia have changed the Toompea Castle to their liking over the last 800 years, starting with the initial stone structure built by the German Knights of the Sword in the 13th century and eventually turning into a tickle-me-pink Baroque palace, courtesy of Catherine the Great. It's now home to the Riigikogu (Estonian parliament), which commemorates the country's independence by raising the national flag atop the 14th-century Tall Hermann tower every morning.

Tourists can take free guided tours of the Toompea Castle in English, Russian, or Estonian on weekdays, with advance reservations. You'll get to explore the inside of the rosy building, hear about its storied past, and learn about the structure of the Riigikolu. After your tour, walk 500 meters northeast to the Patkuli viewing platform for an epic panoramic vista of Tallinn. From here, you can see straight down to the port.
