We arrived in Bratislava, the capital of Slovakia, in the evening. This is a fairly low-key capital. It was originally a fortress built by the ancient Romans. It is now composed of two new and old towns. There are many places of interest in the old town, the oldest and most representative of which is the Bratislava Castle. Interestingly, this ancient city built a UFO viewing platform on the Danube River. The shape and name are completely different from the temperament of the city. Here you can enjoy a complete panoramic view of Bratislava. It is worth mentioning that the platform has no glass and the balcony is flat, so even if there is no tripod, you can take the camera directly on the balcony and shoot it with a lens. The items in the class are raised in the lens, and then shot with a delay of two seconds to minimize camera shake, and you can easily get the exquisite Bratislava night scene.
