Colosseum ASCII Art
A photochrom print of the Colosseum in Rome from the 1890s: the outer wall rises in tiers of arches on the left and the lower, broken inner ring shows on the right, above an open dirt square
The dark border of the print becomes a % frame around the whole result, and the pale sky inside it is an even field of : and . marks. The taller outer wall rises on the left in tiers of + and *, while the lower, broken inner ring stretches to the right. Rows of arches repeat as # and % marks, once in the upper tiers and again in the ground-level arcade, and the open square in front fades to + and *. Photochrom print, 1890s, Library of Congress; ASCII conversion by this site.

- Wikimedia Commons copy of a Library of Congress photochrom print of a landmark. Evidence link Evidence: Exact file record and SHA-1 checked October 28, 2026 UTC. Downloaded unchanged: https://upload.wikimedia.org/wikipedia/commons/8/87/Exterior_of_the_Coliseum_Rome_Italy.jpg.
- File creator
- Photochrom print, between about 1890 and 1900, listed in the Detroit Publishing Company's 1905 catalogue as print 6782; Photochrom Prints collection, Library of Congress Prints and Photographs Division (ppmsc.06601), shared through Flickr Commons. Structure: the Flavian Amphitheatre in Rome, completed in AD 80. Evidence link Evidence: Photographer or publisher, date and Library of Congress identifier are taken from the exact Commons file record, separately from the structure shown..
- License or terms
- Public-domain photochrom print of a structure with no surviving copyright. Evidence link Evidence: The print was published by 1905, before 1931, so it is in the public domain in the United States; the exact record is tagged Flickr-no known copyright restrictions, and the Library lists no known restrictions on reproduction. The amphitheatre was completed in AD 80, long before any copyright system existed. The exact file record lists no additional restrictions. Credits are retained voluntarily. Use as an educational conversion example implies no affiliation with or endorsement by the landmark's owner, operator, photographer or the Library of Congress; it makes no merchandise or trademark use of the landmark's name or image..
- Preparation
- The bundled file is the unchanged Commons original, including its existing framing and color. Sharp applies orientation and sRGB/Lanczos3 sampling for thumbnails and the 100-column Standard preview. The ASCII is a lossy conversion by this site; no image regions are reconstructed. Evidence: scripts/build-example-previews.cjs; exact source and sampled-raster SHA-256 hashes in lib/generated/example-previews.json.
Owner review: PENDING. The exact photograph and separate structure evidence are documented for owner review; this does not clear other photos, night illumination, merchandise or uses implying affiliation.
Standard ASCII
Standard ASCII Art: 100 columns; rows = max(1, round(columns × source height / source width × 0.55)).

Checking destination fit...
README and chat presets use printable ASCII. Unicode blocks and edge lines need matching font support; emoji can occupy different widths on another device. PNG keeps this browser's rendering, not another app's emoji style.
Sharing ASCII art in Telegram? Check monospace formatting and wrapping before sending. Ordinary chat formatting and Bot API HTML are different.
Edge detection
Edge Detection Only: 100 columns; rows = max(1, round(columns × source height / source width × 0.55)).
Edge Intensity: 1. Uses directional Unicode lines, not the selected character ramp.
Brightness 100%, contrast 100%, saturation 100%, hue 0, sepia 0%, inversion off. Dithering does not apply to this mode.
Open this recipe in the editor to keep this source, mode and settings. Browser resampling and fonts can differ from the built preview. Copy/TXT retain text; PNG uses black text on white at 12 px monospace, at least 1.2 line spacing and 20 px padding, independent of screen theme.
Character Optimization matches local glyph shapes in 4x8 cells at 8 px monospace. Compare texture with Standard; it is not a universal quality improvement, and your display font does not change the matching font.
Character Optimization
Character Optimization: 100 columns; rows = max(1, round(columns × source height / source width × 0.55)).
Character ramp: @%#*+=-:. (including a final space).

Mosaic comparisons use 15 symbol columns, not the 100 columns of the character modes. The detailed recipe increases contrast to 150%; choose Coarse mosaic in the editor for the original five-column style.
Detailed emoji mosaic
Emoji Mosaic: sampling width 60, Emoji Size 4, squares set, transparent-cell symbol "⬜". Final columns = ceil(width / Emoji Size); rows depend on source aspect ratio.
Brightness 100%, contrast 150%, saturation 100%, hue 0, sepia 0%, inversion off. Dithering does not apply to this mode.
