Territory of one state located within another. This is very curious, but there are territories within another territory, which only divide streets, houses, bedrooms, etc.
The Fergana Valley
It is shared by Uzbekistan, Tajikistan and Kyrgzstan and is a virtual archipelago of enclaves that pose serious challenges to state sovereignty no. Kyrgyzstan: There is a small town in Kyrgyzstan, Barak, in the region of the Fergana Valley that is located in Kyrgyzstan, Tajikistan and Uzbekistan. The town is surrounded by Uzbek territory and about two square kilometers in size. Tajikistan: There are three Tajik enclaves, all of them in the Fergana Valley. One of them, the town of Sarvan, is surrounded by the territory of Uzbekistan, while the remaining two, the town of Vorukh and a small [unidentified?] Settlement near the Kairagach Kyrgyzstan train station, are each surrounded by Kyrgyz territory. Uzbekistan: There are four Uzbek enclaves, the entire territory of Kyrgyzstan in the interior, in the Fergana Valley. Two of them are the cities of Sokh and Shakhimardan and the other two the small territories of Chong-Kara and Dzhangail. There may be a fifth exclave Uzbekistan within Kyrgyzstan however I have only found a map that supports it (thanks to Nathan). However, the enclaves and exclaves in Fergana are on par with space science in terms of difficulty.
Northwest Angle, Minnesota
The Angle Inlet or Northwest Angle (in Spanish, 'Northwest Angle'), known simply as "The Angle" among the locals, is a small part of the US territory that, with the exception of Alaska and Point Robert, is the only one It is located further north of the 49º N parallel (parallel that marks the northern border with Canada, from the West Coast along the northern borders of the states of Washington, Idaho, Montana, North Dakota, and part of Minnesota).

It is accessed from Canadian territory or by sailing or flying over Lake of the Woods. With the exception of this area, the territory of the 48 contiguous states does not extend further north. Some projections of the American map sometimes create a superficial appearance, extending further north to Maine than to Angle Inlet, which is a mistake. The Northwest Angle.

Jungholz, Austria within Germany.
The summit at more than 1,600 meters of altitude of a mountain marks one of the few places in the world where the borders form a quadrifinuium, that is, a border cross. Jungholz and the rest of the country to which it belongs (Austria) only intersect at a single geometric point. That situation leaves the people as an intruder in Germany, a place that can only be accessed from Austria crossing overseas. One more, but one of the rarest.

Mahda and Nahwa, Oman within the Arab Emirates (and in turn within Oman).
The fried egg of the desert. The United Arab Emirates is a federation whose territorial organization is a strange puzzle product of tribal struggles and disputes, and which was delimited by British surveyors in the fifties of the twentieth century.

The two islands joined naturally due to alluvial sedimentation, so, since the agreement of 18 In June 1988, between the two governments, a dry border has been established on the now Martín García island - Timoteo Domínguez. Other alluvial deposits created the Hercules islets off the northwest coast of Martín García, currently merged and under Uruguayan sovereignty.
Büsingen am Hochrein, Germany within Switzerland.
Büsingen is the only German municipality that has its own registration, and also the only one where the Swiss franc is legal tender, or where residents have the right to Swiss citizenship. The integration of this small German island in Switzerland is total, so much so that until the entry of Switzerland into the Schengen system in 2009 it belonged to the customs system of the Swiss Confederation. The town has Swiss and German postal codes and police from both countries, too. The origin of the enclave dates back to the 18th century, when, after many disputes, Austria sold all the territories around the town to the Swiss canton of Schaffhausen, expressly excluding Büsingen.

Kowloon, walled China inside Hong Kong
The walled city of Kowloon was a Chinese enclave within the British colony of Hong Kong, emerged from the treaty of the late twentieth century by which the British were organizing the colony. The null control that both the Chinese and British could exert over the place led to Kowloon becoming a place outside the law, of any law. In the mid-nineties, when it was dismantled, it was the human settlement with the highest population density in history.
Cooch Bihar, or the recurring enclaves, India and Bangladesh
If Baarle holds the European record, the world record for border mental alienation is in the Cooch Bihar region, between India and Bangladesh. 92 Balngladesian enclaves within India (21 of them within other Indian enclaves in Bangladesh) and 102 Indian enclaves in Bangladeshi territory (three of them in other enclaves, and one of them within a metaenclave) in which seventy thousand people reside whose lives are marked dramatically by the political situation of perpetual tension between two neighbors not too well avenged.
The train enclaves, Germany within Belgium.
One of the rarest borders in Europe. After World War I, the Treaty of Versailles granted Belgium sovereignty over a railway line that ran through German territory and cut at various points with the new border. The situation left up to five pieces of Germany physically separated by just three meters of Belgian territory from the rest of the country. The railroad was dismantled, but the ground through which it circulated remains under Belgian sovereignty.

Baarle, Belgium within the Netherlands within Belgium, and vice versa.
Europe's demented border record is in Baarle Hertog and Baarle Nassau (Belgium and Holland, respectively). Twenty-two Belgian enclaves in the Netherlands and eight Dutch enclaves in Belgium (seven of them within other Belgian enclaves in the Netherlands) make Baarle a place of pilgrimage for border lovers. Breweries in two countries, border killings, banks that could not be inspected and pirate radio stations in two countries, Baarle is full of stories that will drive the geek of the borders in joy.
The smallest metaenclave in the world
The smallest enclave in the world is also in Cooch Bahar. This is an unnamed Bangladeshi metaenclave, which has an area of only 53 m².
It is one of the six European microstates. The Vatican City proper has an area of 0.439 km² (44 hectares), 1 and a population of approximately 900 inhabitants, 2 making it a hybrid city elevated to the rank of independent state, being also the smallest country in the world , and the only one whose official language is Latin. It is so small that only St. Peter's Basilica is 7% of its surface; the basilica and St. Peter's Square occupy 20% of the territory, which makes it the most urbanized independent territory in the world. The Vatican City began its existence in 1929 after the signing of the Lateran Pacts between the Holy See and the then Kingdom of Italy, which in 1870 had conquered the Papal States.

Llivia Spain within France.
Located north of the province of Girona, Llivia is a small town of just over 1,500 inhabitants whose twelve square kilometers of surface are completely surrounded by French territory. It owes its situation to a technicality, being “villa” instead of “town”, when 33 municipalities of Cerdanya were transferred to France in 1660. The situation of the lliviencs was quite uncomfortable until the Schengen Treaty entered into force, in 1995, but it also caused funny situations, such as the War of the Stops.
