Decision. Léa Linster sits at 17 route de Luxembourg in Frisange [1] — ~14 km from the Kirchberg conference belt [2]. Five flagship 2026 events fall inside the 30 km circle and are still upcoming as of May 29, 2026: Nexus Luxembourg (Jun 10–11) [3], ICT Spring (Jun 29–30) [6], Open Source Conference Luxembourg (Oct 7, Belval) [7], hack.lu (Oct 20–23, Dommeldange) [9], and Luxembourg Internet Days (Nov 17–18) [11]. The June ICT Spring and June Nexus weekends are the cleanest pairing with a Saturday dinner at Léa Linster.
Upcoming 2026 events (within 30 km)
| Event | Dates | Venue | km from Frisange | Focus | Sources |

Which one to pair with the dinner?
- Nexus, Jun 10–11 (Wed/Thu) — biggest, flashiest, 4-track “AI/fintech/startup/national” mash-up; finishes Thursday, so a Saturday Léa Linster dinner is a relaxed cap to the week [3].
- ICT Spring, Jun 29–30 (Mon/Tue) — same LuxExpo venue, more enterprise-IT and fintech flavor, ~5,000 pros; the prior weekend (Jun 27–28) is the natural Léa Linster slot [6].
- hack.lu, Oct 20–23 (Tue–Fri) — small, technical, infosec-deep; Dommeldange is the same Luxembourg-City cluster, ~18 km north. Friday wraps in time for a Saturday dinner [9] [10].
- OSC Luxembourg, Oct 7 (Wed) — one day in Belval, theme “Leading by example in Digital Sovereignty”; pair with a Saturday Oct 10 dinner [7].
- Luxembourg Internet Days, Nov 17–18 (Tue/Wed) — Kirchberg, networking-heavy, 1,300+ ICT execs across LUNOG, healthcare IT and municipal-IT tracks [12].

Recurring / not-yet-dated
- Luxembourg Blockchain Week — annual late-November in Kirchberg; most recent was 24–28 Nov 2025; the 2026 edition is expected but unannounced as of this writing [20].
- Monthly developer meetups in Luxembourg City — Vibe-Code & Hack Apps at House of Startups [22], plus DevOps Café, AWS user group, blockchain and digital-transformation circles [23]. A weekend trip can be padded with a Thursday-evening meetup if dates align.
Out of range (>30 km from Frisange)
Worth knowing what you’re not getting:
- Trier (DE) — ~50 km east. No tier-1 IT conference inside 2026, but the Hochschule Trier hosts smaller research events.
- Metz / Saarbrücken — both >45 km; French-Tech-Est events happen in Thionville (~17 km, in range) but no flagship 2026 IT conference confirmed there.
- Brussels (BE) — FOSDEM 2026 (Jan 31 – Feb 1) is the European open-source flagship, but at ~190 km it’s a trip of its own.
How the 30 km circle maps
Frisange anchors the south-central corner of Luxembourg. The circle covers Luxembourg City and its suburbs (Kirchberg, Dommeldange, Limpertsberg), the entire southern industrial belt (Esch-sur-Alzette, Belval, Differdange, Dudelange) and reaches into French Moselle as far as Thionville [2]. It does not reach Trier, Saarbrücken, Metz or Arlon. Public transport across Luxembourg is free, so any Kirchberg/Belval venue is a ~20–30 min commute from Frisange by tram + bus [10].
