Himinbjörg

Where the bridge touches heaven stands Himinbjörg. Grímnismál says Heimdall rules there over the holy fanes and, as the gods’ watchman, drinks the good mead in his tranquil home. Gylfaginning puts it on the border of heaven where Bifröst reaches it. The entry notes that only Snorri sets it at heaven’s edge and has Heimdallr guard the bridge from mountain giants. A watchman’s house stands at a boundary, and the poem still calls it tranquil.
