Star-seeking towers

The Star-seeking towers are the greatest buildings of Neptune in the age of The Last Men: vast, often translucent pylons whose summits serve as the community’s astronomical observatories and whose many other uses bring together contemplation, ritual, recuperation, and physical exertion. Rising above a landscape otherwise dotted mostly with low buildings, they are not merely monuments to one age. Successive cultures have added to their architectural inheritance, making the towers a shared record of the race’s long continuity.

Form and Scale

Most buildings across Neptune’s green countryside are only one story high, but the towers rise like geometrical mountains above the planet’s otherwise level or undulating ground. Their cruciform or star-shaped sections distinguish their forms, and their bases may extend twenty miles or more across. Constructed from adamantine materials made of artificial atoms, they reach heights at which Neptune’s atmosphere is already attenuated.

Many towers are translucent or transparent. When illuminated from within at night, they appear as structures of light. Their scale and materials set them apart from natural mountains, which are absent from Neptune, and from the ordinary dwellings spread across the landscape. The towers are not isolated architectural curiosities: their high summits and broad foundations make them conspicuous landmarks within a world where the human population numbers a million million.

Observatory and Shared Uses

The towers’ summits house hosts of astronomers. From these elevated stations, the community observes the galaxy and more distant universes, seeing itself, in the narrator’s image, as a small raft amid a vast cosmic ocean. The towers therefore provide the essential observational vantage from which the people of Neptune look beyond their immediate world.

They also gather people for symbolic acts the narrator identifies as religious, though no single narrower description captures their meaning. The same heights offer the refreshment of mountain air in a world without natural mountains, while their pinnacles and precipices give many people a place to indulge the inherited human desire to climb. Observatory, temple, sanatorium, and gymnasium are combined in one structure: scientific observation, collective practice, bodily renewal, and exertion occupy the same architectural space.

Architecture Across Cultures

The towers embody the work of The Last Men as a whole, rather than the achievement of one locality. Different structures express different stages in the race’s history, and their styles range from forms a visitor might recognize as Gothic, Classical, Egyptian, Peruvian, Chinese, or American to a thousand architectural ideas unfamiliar to that visitor. The variety records successive cultural expression without reducing the buildings to a single period or style.

A new architectural glory is conceived and built only about once in forty thousand years. Yet the continuity of the cultures has been such that earlier work has scarcely ever needed to be removed. Some towers are almost as old as the species, while others remain unfinished. Their accumulated forms thus join works separated by immense spans of time in an inhabited, ongoing architectural inheritance.

Significance

The Star-seeking towers make the history and organization of The Last Men legible in monumental form. Each is at once a practical instrument for astronomy and a setting for communal and individual pursuits; each also bears the expression of a culture that belongs to the race’s larger history. Their functions resist a strict separation between scientific observation, religious symbolism, health, and recreation.

Their upward reach answers to the community’s outward gaze: from a built world on Neptune, astronomers look toward remote universes, while generations continue to add their own forms to the towers below. The structures make both scales visible—the vastness beyond the planet and the long continuity of the people who inhabit it.
