1. 宁平三叠关概述
宁平三叠关 如同一条飘逸的绿色丝带，连接着两片土地，创造出独特而难以在别处找到的景致。关口位于宁平省和清化省的边界线上，三叠山脉绵延二十多公里，宽度从2公里到7公里不等，是连接北部和中部地区的天然节点。
三叠关是位于三叠山脉上的一组关口，作为宁平省和清化省之间的天然分界线。在行政区划上，该区域位于宁平省三叠市与清化省碧山县和河忠县的交界处。历史上，古老的千里路曾穿过此关，但如今国道1号已改道并从Xay坡越过三叠山脉，不再经过古老的关道。
由于行政区划的划分，在三组古老的关口中，目前只有北部关口属于宁平省三叠市，而中部和南部关口则属于清化省碧山县。这里的地貌既有石灰岩山脉，也有泥土丘陵，形成了从和顺省一直延伸到东海沿岸的最后一道石灰岩弧线。
宁平三叠关 在连接红河三角洲与马江三角洲方面发挥着重要作用。险峻的地形和三座相连的大山形成了三个连续的关口，因此民间称此地为“三叠关”，意为三个相连的层次。
宁平三叠关 的历史价值体现在1789年抗清战争中的三叠-边山防线。这是西山朝选择的重要防御据点，与光中皇帝和吴时任将军的战功紧密相连。

2. History, culture, and anecdotes about Tam Diep Pass Ninh Binh
2.1. Name, origin, and meaning
The name Tam Diep Pass Ninh Binh carries profound historical and cultural meanings of the nation. "Tam Diep" means "three layers" or "three tiers," emphasizing the topographical characteristic of three overlapping mountain passes. Locals often call it by the simple, familiar name "Deo Ba Doi," filled with deep affection.
The image of Tam Diep Pass Ninh Binh has also appeared in ancient poetry, notably through the verses of the female poet Ho Xuan Huong, depicting the majestic beauty of the mountains and forests here.
2.2. Role as a historical defense line
Tam Diep Pass played an extremely important role as a historical defense line, most notably in the late 18th century during the resistance against the invading Thanh army.
When 290,000 Thanh troops invaded our country in late 1788, the Tay Son generals Ngo Thoi Nham and Ngo Van So advocated a strategic retreat to this location, establishing the Tam Diep - Bien Son defense line. This was the final withdrawal limit, tasked with the crucial mission of halting the enemy's advance and ensuring the safety of the rear. Immediately after, this defense line became the assembly point for the main army of King Quang Trung (from January 15 to 25, 1789) before he led the lightning campaign to the North to decisively defeat the Thanh army.
Earlier, in the 16th century, the Le-Trinh regime also utilized this rugged terrain to build ramparts, turning Tam Diep Pass into the boundary between the Southern and Northern courts. The forts and ramparts here continued to be used during the Nguyen dynasty to control the vital North-South arterial road.
2.3. Relics and cultural imprints through time
In 1842, during a tour to the North, King Thieu Tri, a Nguyen monarch with a romantic soul, was moved by the scenery here and composed the poem "Qua Tam Diep son" (Passing through Tam Diep mountains) with a heroic tone. Today, if one follows the legendary ancient Thiên Lý road up to the summit of Ba Doi Pass, visitors can admire the Ba Doi stele house. This is where a stone stele bearing the Han inscription "Ngự chế thi nhất thủ" (Imperial poem, one piece) and the full text of the king's poem from that era are preserved.
Relics such as earth ramparts, temples dedicated to Tay Son soldiers, and places like "Go Cam Co" (Flag Planting Hill) and "Go An Thu" (Edict Reading Hill) still exist today. These are vestiges of the ancient defense line and also serve as places to commemorate the contributions of King Quang Trung and the patriotic soldiers. Tam Diep Pass Ninh Binh was once the natural and administrative boundary of the Nguyen dynasty, associated with many legends of battles and sacred stories in folklore.

3. Geographical Structure and Landscape of Tam Diep Pass Ninh Binh
3.1. Structure of Three Characteristic Passes
Tam Diep Pass Ninh Binh is favored with a terrain consisting of three large passes, tiered like three sturdy steps amidst the mountains and forests. North Pass is located near Tam Diep city with a height of about 75 to 80 m, serving as the first point welcoming tourists from the North. From this position, tourists can easily observe the panoramic mountain scenery and it is also a favorite resting spot.
Middle Pass, with a height of 110 m, is the highest among the three passes, concentrating many historical traces and primeval forests. This area is considered the "heart" of Tam Diep Pass Ninh Binh, preserving many heroic stories and spectacular natural scenery. South Pass, with a height of 80 to 90 m, is located in Bim Son, Thanh Hoa, playing an important role in connecting the southern localities.
3.2. Majestic Limestone Mountain Nature
The mountain range of Tam Diep Pass stretches over 20 km, with many peaks reaching nearly 200 m, and the highest peak reaching 570 m in the northwest bordering Hoa Binh. The terrain is mainly limestone, creating jagged mountain masses, interspersed with small valleys and cool streams.
The current majestic natural landscape of Tam Diep Pass has changed significantly from its former wild and rugged appearance. Today, the landscape on both sides of the Thien Ly road through the pass has less undergrowth, replaced by beautiful, lush green hillsides cultivated with crops such as pineapple, lychee, and longan.
However, the majesty of the pass remains. Upon reaching the summit, tourists will stand amidst a vast, high, and green natural space, and from here, they can gaze down at the tranquil beauty of Canh Chim Lake below.
