The name Jungfrau ("maiden, virgin"), which refers to the highest of the three prominent mountains overlooking the Interlaken region, along with the Mönch ("monk") and the Eiger ("ogre"), is most likely derived from the name Jungfrauenberg given to Wengernalp, the alpine meadow directly facing the huge northern side of the Jungfrau, across the Trummelbach gorge.

[3] But from Lake Thun, and the greater part of the canton of Bern, it is the most conspicuous and the nearest of the Bernese Oberland peaks; with a height difference of 3,600 m (11,800 ft) between the summit and the town of Interlaken.

The Jungfrau is the westernmost and highest point of a gigantic 10 km (6.2 mi) wall dominating the valleys of Lauterbrunnen and Grindelwald.

In contrast to the vertiginous precipices of its northwest, the mountain's southeastern side emerges from the upper snows of the Jungfraufirn, one of the main feeders of the Aletsch Glacier, at around 3,500 meters (11,500 ft).

[4] In 1811, the brothers Johann Rudolf (1768–1825) and Hieronymus Meyer, sons of Johann Rudolf Meyer (1739–1813), the head of a rich merchant family of Aarau, along with several servants and a porter picked up at Guttannen, first reached the Valais by way of the Grimsel, and crossed the Beich Pass, a glacier pass over the Oberaletsch Glacier, to the head of the Lötschen valley.

There, they added two local chamois hunters, Alois Volken and Joseph Bortis, to their party and traversed the Lötschenlücke before reaching the Aletschfirn (the west branch of the Aletsch Glacier), where they established the base camp, north of the Aletschhorn.

After an unsuccessful attempt, defeated by bad weather, in the course of which the Oberaarjoch was crossed twice (this route being much more direct than the long detour through the Lötschental), Rudolf, with the two Valais hunters (Alois Volker and Joseph Bortis), a Guttannen porter named Arnold Abbühl, and a Hasle man, bivouacked on a depression on the southeast ridge of the Finsteraarhorn.

Next day (August 16) the whole party attempted the ascent of the Finsteraarhorn from the Studer névé on the east by way of the southeast ridge, but Meyer, exhausted, remained behind.

In 1863, a party consisting of three young Oxford University graduates and three Swiss guides successfully reached the summit and returned to the base camp of the Faulberg (located near the present position of the Konkordia Hut) in less than 11 hours[7] (see the section below, The 1863 Ascent).

Having spent the night on the rocks of the Schneehorn (3,402 m or 11,161 ft) they gained next morning the Silberlücke, the depression between the Jungfrau and Silberhorn, and thence in little more than three hours reached the summit.

The more difficult and dangerous northeast ridge that connects the summit from the Jungfraujoch was first climbed on 30 July 1911 by Albert Weber and Hans Schlunegger.

The foreign climbers were long thought to have been John Tyndall, J. J. Hornby and T. H. Philpott, until in 1958 the records were checked by the Alpine Club and the following conclusion was reached: On July 23, 1863, Phillpotts, with James Robertson and H.J.

The entry in Peter Baumann’s Führerbuch (facsimile in A.C. archives) says that the trio crossed the Strahlegg Pass and the Oberaarjoch, and then climbed the Jungfrau from the Eggishorn.

[15] William Robertson (1839–1892), the leader of the expedition (wrongly called 'James' in the Note quoted above), was an Australian by birth, and the first non-British national to take part in the Oxford and Cambridge Boat Race.

[15] A description of the ascent of the Jungfrau is contained in a letter dated Sunday 26 July which Phillpotts wrote to his friend Alexander Potts (later to become the first headmaster of Fettes College).

The Virgin certainly did not smile on the poor "fools who rushed in" on her sacred heights, i.e. in plain British, we had the treadmill slog, the biting wind, the half frost-bitten feet and the flayed faces that generally attend an Alpine ascent.

The Upper Hole in which we lodged just contained Chay[tor], the Guv [Robertson] and myself, stretched at full length on a little hay over a hard rock mattress, convex instead of concave at the point where one likes to rest one's weight.

At two we got up and methodically put our feet into the stocks, i.e. our boots, breakfasted and shivered, then started (unwashed of course, as the cold gave us malignant hydrophobia) a little after 3:30.

Rubi led, and off we went, roped and in Indian file, in the old treadmill way over the slippery plowed-field-like snow that lay on the upper glacier, for a pull without a check of one or two hours.

Some twenty or thirty steps, some cut, some uncut, soon took us up a kind of hollow, and we got on a little sloping plateau of some six feet [1.8 m] large, where we left the grub and the knapsack, keeping my small flask of cognac only.

Suddenly there burst upon us, on lifting our heads over the ridge, the green and cheerful valleys of Lauterbrunnen and Interlaken, of Grindelwald and a distant view of others equally beautiful stretching on for ever in one vast panorama.

In 1893, Adolf Guyer-Zeller conceived of the idea of a railway tunnel to the Jungfraujoch to make the glaciated areas on its south side more accessible.

The goal was in fact to reach the summit of the Jungfrau with an elevator from the highest railway station, located inside the mountain.

The train enters the Jungfrau Tunnel running eastward through the Eiger just above Eigergletscher, which is, since 2020, also accessible by aerial tramway from Grindelwald.

Before arriving at the Jungfraujoch, it stops for a few minutes at two other stations, Eigerwand (on the north face of the Eiger) and Eismeer (on the south side), where passengers can see through the holes excavated from the mountain.

[18] The Schilthorn above Mürren, the Männlichen above Wengen, and the Schynige Platte above Wilderswil, offer good views of the Jungfrau and the Lauterbrunnen valley.
