Historians believe it was a temple dedicated to all the gods, hence the name <em data-start=\"1666\" data-end=\"1676\">Pantheon<\/em>, from the Greek meaning \u201call gods\u201d, but exactly how it was used is still debated.<\/p>\n<p data-start=\"1537\" data-end=\"1757\">Unlike many ancient ruins in Rome, the Pantheon is not just a monument to the past. Indeed, one of the main reasons it remains in such remarkable condition is that it has never fallen out of use and into ruin.<\/p>\n<p data-start=\"1537\" data-end=\"1757\">In 609 AD, it was consecrated as a Christian church, saving it from the fate of many ancient Roman monuments, which were dismantled for building materials over the centuries.\u00a0So, it has been used as a Christian church since the 7th century &#8211; and you can still attend worship there on Sundays if you want to take in one of the most unique and breath-taking sanctuaries on earth.<\/p>\n<p data-start=\"1759\" data-end=\"2010\">Today, it remains a symbol of Rome\u2019s incredible ability to preserve its past while continuing to live in it.<\/p>\n<div class=\"relative w-full overflow-visible\">\n<section class=\"text-token-text-primary w-full focus:outline-none [--shadow-height:45px] has-data-writing-block:pointer-events-none has-data-writing-block:-mt-(--shadow-height) has-data-writing-block:pt-(--shadow-height) [&amp;:has([data-writing-block])&gt;*]:pointer-events-auto [content-visibility:auto] supports-[content-visibility:auto]:[contain-intrinsic-size:auto_100lvh] R6Vx5W_threadScrollVars scroll-mb-[calc(var(--scroll-root-safe-area-inset-bottom,0px)+var(--thread-response-height))] scroll-mt-[calc(var(--header-height)+min(200px,max(70px,20svh)))]\" dir=\"auto\" data-turn-id=\"request-69fa006a-7eb0-8327-a8dd-425ff22859a9-24\" data-turn-id-container=\"request-69fa006a-7eb0-8327-a8dd-425ff22859a9-24\" data-testid=\"conversation-turn-110\" data-scroll-anchor=\"false\" data-turn=\"assistant\">\n<div class=\"text-base my-auto mx-auto pb-10 [--thread-content-margin:var(--thread-content-margin-xs,calc(var(--spacing)*4))] @w-sm\/main:[--thread-content-margin:var(--thread-content-margin-sm,calc(var(--spacing)*6))] @w-lg\/main:[--thread-content-margin:var(--thread-content-margin-lg,calc(var(--spacing)*16))] px-(--thread-content-margin)\">\n<div class=\"[--thread-content-max-width:40rem] @w-lg\/main:[--thread-content-max-width:48rem] mx-auto max-w-(--thread-content-max-width) flex-1 group\/turn-messages focus-visible:outline-hidden relative flex w-full min-w-0 flex-col agent-turn\">\n<div class=\"flex max-w-full flex-col gap-4 grow\">\n<div class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal outline-none keyboard-focused:focus-ring [.text-message+&amp;]:mt-1\" dir=\"auto\" tabindex=\"0\" data-message-author-role=\"assistant\" data-message-id=\"37b99d8c-8940-4b1c-b84e-95ceef22f9ca\" data-message-model-slug=\"gpt-5-5\" data-turn-start-message=\"true\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden\">\n<div class=\"markdown prose dark:prose-invert wrap-break-word w-full light markdown-new-styling\">\n<blockquote>\n<p data-start=\"0\" data-end=\"307\" data-is-last-node=\"\" data-is-only-node=\"\"><strong data-start=\"0\" data-end=\"16\" data-is-only-node=\"\">Insider Tip:<\/strong> The <a class=\"decorated-link\" href=\"https:\/\/www.walksofitaly.com\/blog\/attractions\/the-trevi-fountain-in-rome?utm_source=chatgpt.com\" target=\"_new\" rel=\"noopener\" data-start=\"21\" data-end=\"134\">Trevi Fountain<\/a> is just a short walk from the Pantheon and makes the perfect next stop.

Far more than just a dramatic design element, it is the building\u2019s only source of natural light, creating a moving beam of sunlight that slowly travels across the marble interior throughout the day like a giant celestial spotlight.<\/p>\n<p data-start=\"570\" data-end=\"921\">This ever-changing light was carefully designed to enhance the Pantheon\u2019s spiritual atmosphere, connecting the building to the heavens above. It also means the Pantheon is open to the elements, so when it rains, water falls directly through the oculus into the building. If you take a close look you\u2019ll see that drainage holes are cut into it allowing rainwater to drain away without puddling on the stone and doing lasting damage.<\/p>\n<p data-start=\"923\" data-end=\"1253\" data-is-last-node=\"\" data-is-only-node=\"\">Beneath this extraordinary dome lies another treasure: the tomb of <span class=\"hover:entity-accent entity-underline inline cursor-pointer align-baseline\"><span class=\"whitespace-normal\">Raphael<\/span><\/span>, one of the greatest artists of the Renaissance, who specifically requested to be buried here. His presence adds yet another layer of significance to a building already overflowing with history, art, and architectural genius.<\/p>\n<blockquote>\n<p data-start=\"923\" data-end=\"1253\" data-is-last-node=\"\" data-is-only-node=\"\"><strong data-start=\"0\" data-end=\"16\" data-is-only-node=\"\">Insider Tip:<\/strong> If visiting the Pantheon has sparked your curiosity about ancient Rome, don\u2019t stop here.

It seems, from contemporary writings, that \u201cPantheon\u201d may have only been a nickname for the building, but what it was actually called and what purpose it was meant to serve is still a matter of conjecture.<\/p>\n<p><strong>Filippo Brunelleschi studied the Pantheon<\/strong> when he was trying to figure out how to construct the massive Dome on the <a href=\"https:\/\/www.walksofitaly.com\/blog\/attractions\/florence-cathedral\">Florence Cathedral<\/a>.<\/p>\n<p><strong>The Renaissance master Raphael is buried in the Pantheon,<\/strong> as mentioned above. But less well known is that his fianc\u00e9 is buried beside him. The story goes that Raphael was engaged to be wed to Maria Bibbiena but put off the marriage for six years (carrying on at least one affair in the meantime) until she died. It appears that Rafael\u2019s motivations for marriage were basically connections.<\/p>\n<p><strong>The bronze that Pope Urban VIII removed from the Pantheon went into the making of cannons for the Castel Sant\u2019Angelo<\/strong>. Not all Romans were particularly happy about it. A contemporary poem quipped: \u201cWhat the barbarians did not do, the Barberinis did\u201d. (Barberini was the last name of Urban VIII before he became pope.) It is also rumoured that it also went into Bernini\u2019s divine baldachin, but that is another story!<\/p>\n<div id=\"attachment_24853\" style=\"width: 1630px\" class=\"wp-caption alignnone\"><img decoding=\"async\" aria-describedby=\"caption-attachment-24853\" class=\"wp-image-24853 size-full\" src=\"https:\/\/www.walksofitaly.com\/blog\/wp-content\/uploads\/2026\/02\/Walks_Rome_ColosseumExpress_WEB-RES-0009.jpg\" alt=\"\" width=\"1620\" height=\"1080\" srcset=\"https:\/\/www.walksofitaly.com\/blog\/wp-content\/uploads\/2026\/02\/Walks_Rome_ColosseumExpress_WEB-RES-0009.jpg 1620w, https:\/\/www.walksofitaly.com\/blog\/wp-content\/uploads\/2026\/02\/Walks_Rome_ColosseumExpress_WEB-RES-0009-768x512.jpg 768w, https:\/\/www.walksofitaly.com\/blog\/wp-content\/uploads\/2026\/02\/Walks_Rome_ColosseumExpress_WEB-RES-0009-1536x1024.jpg 1536w\" sizes=\"(max-width: 1620px) 100vw, 1620px\" \/><p id=\"caption-attachment-24853\" class=\"wp-caption-text\">Local knowledge from expert guides really helps visitors make sense of thousands of years of history!<\/p><\/div>\n<h2><span class=\"ez-toc-section\" id=\"FAQs_%E2%80%93_Visiting_The_Pantheon\"><\/span>FAQs &#8211; Visiting The Pantheon<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3 data-section-id=\"6mf3z7\" data-start=\"137\" data-end=\"187\"><span class=\"ez-toc-section\" id=\"Why_does_the_Pantheon_have_a_hole_in_the_roof\"><\/span>Why does the Pantheon have a hole in the roof?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p data-start=\"189\" data-end=\"522\">The famous opening at the top of the dome, called the oculus, was an intentional part of the original design.
